Worst Four Discount Digital Cameras Buying Mistakes

By Jake Sanders

People make mistakes and most Camera Buying is a living testament to that statement. Most people thought that if they knew about Megapixel and Zoom stuff then they dont have to worry the other features- which proved to be a terrible mistake. So before you purchase that Digital Camera in your head, here are the four mistakes in buying Digital Camera that you might want to avoid encountering.

1. Purchasing the Camera without using it first

Reviews, Specs, Features, and Comparisons are some of the basis in buying Digital Camera today and people seem to be easily caught up with this presentation. You need to like the camera first. Even if you order it online, the best advice I could give you is to hit your local camera store first and handle the camera model you have set eyes upon. The cameras online are presented with extra-emphasis littered with flowery word to seduce you but meeting that camera model beforehand will make that big difference. Try to do specific tasks, and see how hard the camera controls are to navigate.

2. Buying the Most Expensive Model

It is said that prices comes with corresponding quality based on how expensive the purchase is. Sure, who wouldnt choose the coolest, slickest, and sophisticated-looking cameras if you can afford it? But make sure it fits you. For example, if you're new to photography you sure you can maneuver those advanced digital SLR boasting lots of manual controls? I dont think so. It's better to look within your budget, but focus on finding the best camera for your specific needs.

3. Megapixels Exclusivity

A 10.2 Megapixel camera will prove attractive beside a 7.2 Digital Camera Model. It is only natural because we want the best to meet our expectations but also remember that Megapixel shouldnt be the only consideration. You can find 10.2 megapixel cameras that have only 3x zoom while some 7.2 models have four. And 10.2 megapixel pictures consume more space than that of 7.2s in your computer. Think beyond megapixels, because another feature (such as zoom) could be much more important for you.

5. Unsure of What You Want in a Digital Camera

Before purchasing that digital camera, you should know and why do you want that specific model. Because if you only buy camera for the sake of having a camera then thats worst than ordering food for the sake of having food. You need to know what uses or features you want the most reflecting your lifestyle. Consider making a list of your three most important features, and then rank them. That way, you can work on finding a camera that meets those needs first, and worry about extra features later.

Canon Powershot A590is

By Don Bethune

Most people have different ways of picking a digital camera. Perhaps they try each one out in the shop, or ask family and friends which camera they'd recommend. All of these ways are good, and they'll help you pick a nice digital camera.

I find that I prefer to shop around, and check out the features of a wide variety of cameras. My criteria are good features, high quality and low cost. The Canon Powershot a590is is the camera that suits me the best.

The camera is affordable, since it only costs between 80 and 300 dollars. I bought mine online, as they were offering the best deal at the time. Buying online means that the prices are usually cheaper than in stores, but shop around to find the best bargain.

While this camera doesn't cost a lot, it's a really good camera for the money. The quality and ease of use are excellent, and I think the price is very reasonable. All I had to do was read through the manual quickly, and then I was taking beautiful pictures.

There's another Canon Powershot camera, the a570is. There's a few places on the internet where they compare this camera to the a590is. The reviews say that when it comes to a570is vs a590is, they are both good. I prefer the a590is

In truth, though, I don't think you could go wrong with either of these cameras. They are both high quality, and the stunning pictures means that they are worth more than what you pay for them. The photos it takes look professional.

The canon powershot a590is features include, shutter-priority, aperture-priority, image stabilization (anti-shake), snapshooter, a zoom lens, 2.5-inch LCD screen, and internal memory. The canon powershot a590is takes AA batteries. It can take CompactFlash, Memory Stick, xD-Picture Card, or Secure Digital/MultiMediaCards. You can use those sort of things for transferring your pictures to another device such as you computer.

There are other canon a590is reviews on the internet, if you search for them. I found that they were helpful when I was selecting my camera. The reviews let you make up your own mind which is the best camera for you.

Recommended Digital Camera Printers

By Dan Feildman

Having saved hundreds or even thousands of photos in your PC memory, you may start to wonder how you are going to print some out, rather then just using up you hard disc memory. You can really feel great about your digital image collection when you can feel them physically in your hands. Let's discover the options you actually have to print off some of your favorite digital photos.

Printers can either be connected to a digital camera or a computer, with outstanding results. The managing of this software is straightforward enough and you will just need to learn a few basic commands. If you are used to digital gadgets then you will just be able to get started right away, but if this is all new to you, then you should find a step by step guide to speed up the learning process.

Buying a digital camera printer, maybe the first step that you need to take, so take a look at both options to find which most suits your digital needs. Once you have decided on a digital camera printer, take a look on Google or Photography sites for reviews. If that is enough to make a decision, then have a look for the model on the internet in sites like Amazon and eBay and compare prices and delivery charges. Consider opening up a Paypal account for safe online shopping and always check your guarantee period, so you are not too late if you need a refund.

4 and 6 color ink models are available with talk of an 8 ink jet color model to be released shortly. The more ink colors used, the higher the quality of the printed photos become, so to produce the best results then always purchase high weight photo paper and even better if you can afford a 6 ink color digital camera printer.

Other than the type of printers, there are some different printing methods and styles used by the digital camera printers. It is also important for you to understand them. The printing methods can be identified as Ink jet and Thermal. The Ink jet printers are not able to give the user an excellent quality of photographs. In spite of this fact, the Ink jet digital camera printers are used most commonly. The Thermal printing style produces much better results. It applies a waterproof coating on the image. Some users also rank it to be quite cost effective in comparison to the Ink jet printers. This is because of the fact that the cost of paper and the ink cartridges is quite cheap and affordable.

Using a digital camera printer is quite an easy task, once you understand its features and working. You just need to connect it properly. Check if it is compatible to your digital camera before starting to use it. The best part of the digital camera printers is that they do not require a computer to function. They can print directly from the digital camera.

Surveillance Camera Systems in A Bad Economy

By Marcelo Oleas

Hard economic times unfortunately tend to bring an increase in crime. Whether you are a retail business or a corporate office, you are always at risk of some form of crime. For this very reason, surveillance camera systems are no longer a luxury, but more of a necessity.

With our country being in an economic crisis, every penny counts. Every business owner needs to retain as much of their profit as possible and put an end to any possibility of loss. Most people do not even realize that the majority of business shrinkage is a direct result of internal theft and yet most people focus on preventing external theft. Internal shrinkage is one of the the biggest culprits of why business go bankrupt, employees are layed off, and benefits and bonuses are cut.

Surveillance camera systems are like employees that work 24/7, never get tired, never call in sick, and never forget a thing. Without these systems, it is physically impossible for business owners to have a constant eye on their premises without spending a lot of money on around the clock trusted employees. Now with a simple click of a button you can view any captured footage and have actual proof of any wrongdoing.

After losing jobs and incomes being drastically cut, some people unfortunately fall into temptation and shoplifting becomes their easy solution. Stealing food from restaurants and markets or stealing merchandise from retail stores becomes a common task. This is why it is important for business to be alert and prepare themselves with the use of surveillance camera systems.

Surveillance camera systems have been a great aid at capturing and prosecuting criminals. Bank robbers have been caught. Murderers have been prosecuted. And even mysterious crimes have been solved due to the unexpected footage captured by surveillance systems.

Today's variety of surveillance camera systems are endless. You can have something that is very small and basic to something that seems like it came straight from a James Bond movie. No matter the size of your business, with today's technology it is now possible to find the perfect system for any individual needs.

As far as interior cameras, there are even register cameras and wireless cameras. There are the hidden cameras that can be used where needed too.

Designing the right surveillance camera system to best suit your business needs is essential. There are many factors to consider ranging from floor plans, lighting, interior/ exterior use, number of cameras, and much more. It is always highly recommended to have your system professionally designed and installed.

CCD sensors boost frame rates

CCD sensors boost frame rates

By Ann R. Thryft, Contributing Technical Editor -- Test & Measurement World, 2/1/2009

Marketing manager
Eastman Kodak, Image Sensor Solutions

Progressive-scan cameras used in semiconductor and electronics inspection produce images of objects moving down an assembly line by imaging an entire object in one shot, a process that generates high-quality images but tends to create manufacturing bottlenecks. As engineers demand faster camera frame rates to speed up production line throughput, manufacturers of progressive-scan cameras are designing new sensors to improve camera performance. Michael J. DeLuca, marketing manager for Eastman Kodak's Image Sensor Solutions group, discussed how newly designed progressive-scan CCD image sensors can boost frame rates and image quality while lowering system costs.

Q: What are engineers looking for in progressive-scan cameras?

A: In semiconductor and electronics inspection, there's always a need for faster frame rates and higher resolution. Users also want greater sensitivity (meaning the ability to get clear images at low light levels) as well as reduced costs. On top of all this, cameras need to match standard optical formats, such as 1/2 in. and 2/3 in., since this increases compatibility with a wide range of lenses.

There is also a trend toward smaller lenses, since they weigh less, cost less, and take up less space than bigger lenses.

Q: How can image sensors help improve camera performance?

A: You can improve imaging performance by reducing pixel size to get more pixels in the same area. For example, one of the new sensors in our Interline CCD family, the KAI-02050, is a 2-Mpixel, 1600x1200 device in a 2/3-in. optical format. Because it is based on a 5.5-micron pixel, about half the size of our previous-generation 7.4-micron pixel, the sensor contains twice the number of pixels in the same optical format as before.

Alternatively, you can get the same number of pixels in a smaller optical format, which helps reduce camera size and allows the use of smaller and less expensive optics. For example, another member of this family, the KAI-01050, fits 1 Mpixel in a 1/2-in. optical format, instead of the 2/3-in. size necessary for the previous-generation 1-Mpixel sensor.

We also increased the potential frame rate of all the sensors in this family by doubling the number of outputs, which helps improve system throughput. The KAI-02050, for example, operates at a maximum 68 fps, compared to 35 fps in the previous-generation 2-Mpixel sensor.

Q: What else can be done to improve progressive-scan cameras?

A: Camera makers also want the ability to leverage camera electronics across multiple models to help reduce cost. This can be achieved by basing several sensors on the same design platform, using the same ceramic package that contains the sensor chip, and using the same electrical pin definitions, making them all plug compatible. This is true of the sensors in this family. Because the sensors operate the same way, it's easy for camera manufacturers to leverage an existing design when a new sensor becomes available, bringing a new camera and its new sensor technology to market faster.

In addition, since smaller pixels can't collect as much light as bigger pixels, they aren't usually as sensitive under low-light conditions. In moving to this new technology platform, however, we made sure that key imaging parameters like sensitivity and dynamic range stayed the same.

Cal Sensors offers high-sensitivity thermal imaging array

Cal Sensors offers high-sensitivity thermal imaging array

-- Test & Measurement World, 2/5/2009 7:00:00 AM

Extending its line of lead salt detectors, Cal Sensors has introduced the LIRA5S, a lead selenide (PbSe) thermal-imaging array that boasts high sensitivity and a wide wavelength range. The device combines a 256-element multiplex array and an ROIC (readout integrated circuit) in a standard 28-pin package.

The LIRA5S can be used in a variety of high-speed thermal-imaging applications, including hot-spot detection in manufacturing and assembly process lines. It is sensitive in the wavelength region of 1.0 µm to 5.5 µm. Data readout speed is 4 MHz, allowing for fast data analysis.

"LIRA5S can measure up to 256 discrete thermal points and provides sensitivity at longer wavelengths than alternative detector materials, such as InGaAs, which enables accurate temperature measurements of cooler objects," said Brian Elias, director of engineering at Cal Sensors. "Previously, lead selenide arrays with this type of sensitivity were created only for customized solutions and required external electronic systems, as well as several months lead time to produce. LIRA5S provides design engineers with superior sensitivity, extended wavelength, and integrated electronics in an industry-standard package with two to four weeks lead time."

How To Buy A Digital Camera

By Michael Thompson

A really good digital camera is what everyone is looking for, and getting a good camera starts with knowing what you need. Imagine spending $150 and feeling great about the deal you got, but you then realize that this camera is not enough for which you need! Here are some of the things you need to know about in order to choose the right cheap digital camera.

The megapixel tells you only how many megapixels the camera has. The reason camera salesman talk about the megapixel is because it's an easy point of reference to try to upsell you. The reality is that the lens quality and the light sensors make a more significant impact than the megapixels. The thing is, it's hard for a consumer to understand all of the differences between lens quality and light sensors.

The 3.1 mega pixel prints a perfect 8x10, but the new standard is 7-8 mega pixels. Unless you are a pro photographer, then anything over 3.1 is great. Consider a camera in the 6 pixel range. You can get a super price.

The next thing you wanted to is pick the right physical configuration of the camera. You may be spending more than you need if you buy more camera than you can handle. The pro models are very cool, but be realistic about what you are going to do with the camera!

A Digital Single Lens Reflex typically has a larger body and a detachable lens. For many of you reading this article, the DSLR camera is more camera than you'll ever need. Here are the pros, the DSLR will take better pictures. The con is that this will take much more time to learn to use.

Point-and-shoot cameras are smaller, the lens is usually attached, and the lens actually retracts back into the camera base. These are the cameras sold at all big box retailers and electronic stores. You can find many in the few hundred dollar range.

The pros with a point and shoot camera. The prices are much cheaper and affordable. Cons-the camera may not be repairable and goes out of date quickly. Usually is cheaper to just replace the camera instead of repairing.

Think for a few minutes about what kind of camera you need. Knowing that the mega pixel range these days is more than the average person needs. Talk with others that own cameras, and be honest with yourself about the realities of what you are going to do with the camera.

Get The Latest Digital Camera Accessories Cheap And Online

By Sylvia Howard

If you own a digital camera, chances are you will need accessories to go with it. Probably, you are little bit confused about where you should get the ones that you need.

Digital camera accessories are of many types, and are often quite easy to buy in local electronics shops. But when buying in shops, you may not be exposed to the full breadth of available options, and you may end up buying accessories that are not optimal to your needs.

The Internet is probably a better place to buy digital camera accessories. Not only will the choice be much bigger, but you will also have a wealth of information on your fingertips about different kinds of options. And lat but not least, prices will be lower.

Digital cameras are truly wonderful, a great step forward compared to their analogue counterparts. But it still makes a lot of sense to equip yourself with digital camera accessories to maximize your chances of taking the best pictures.

You can find all sorts of things when you search for a digital camera accessory using your favorite search engine. You can find cases, bags and straps so that you can carry your camera with you at all times in security. You can find memory cards and extra batteries or chargers to extend the autonomy of your digital camera. There is a lot to add to your digital camera, but it can also mean that you will be spending a lot of money.

As an alternative to an online retailer you can try an Internet auction site, such as eBay, where you can bid on the digital camera accessory that may be second hand, but also new, as there are lots of small specialized retailers selling new items on auction sites. Chances are you will get the desired digital camera accessory for a ridiculous price.

Check the Internet right now to browse through all the latest digital camera accessories and decide which ones you want to add to your photographer's arsenal. Quality camera accessories can help you take better pictures quickly.

There is an active second hand and used accessory market on the internet that offers the buyer a great opportunity to buy, trade, exchange and recycle. For instance, professional grade SLR lenses are designed and manufactured with precision and durability in mind, and often people 'outgrow' their current lens set and need to replace part of it. So, buying second hand lenses is a real viable option.

However, any online purchase must be accompanied by the necessary research in pricing, and awareness of the risk of fraud and on how to counter it. Most auction sites and online notice boards for used digital camera accessories have valid sections on how to avoid being scammed.

Uses For Disposable Cameras

By Charlie Reese

I have a really great digital camera, and I rarely think about using anything else. However, I have found that there are times when I needed to use something else, and finding disposable cameras have helped me when that is the case.

It is not always a good idea to take your expensive digital or film camera wherever you go. That is when the disposable version is a great idea. Even if you have not run into this yet, you may think more about it in the future depending on where you are going and what you will be doing.

Though you will not get the same quality out of disposable cameras that you would get out of your five hundred dollar digital, you are going to find times when you dont want to take the chance. You may be surprised to find that the disposable camera can give you a pretty good picture, even if not quite up to par with what you are used to getting. These snapshots are going to do the job however, and are great when any type of water may be involved in your outing. Whether you are going to the lake, or are going out on a day that may include rain, try the disposable.

You may also want to use disposable cameras when you are going to a huge event. If you have a small digital, you may have better luck protecting your camera, but those that are larger can be targets for thieves. Even when you have your digital around your neck, it is in danger of being taken from you. When going to concerts where there is going to be low light, or huge outdoor festivals, you should think about taking disposable cameras with you. If they are lost, you are not out a lot of money, and the only thing you lose are the pictures.

Disposable cameras are also great when you are introducing your children to photography. I dont know about you, but I have a hard time handing my expensive digital over to a child who is only three or four years old. They may be very good with them, but you will find yourself hovering over them. Instead, get them something that they can run wild with, even when they are outdoors. They can experiment without you standing right over them, and you wont have many worries about what happens if they drop it or even lose it.

What is the Digital Camera?

By Charlie Reese

The developments in technology are not like vacuum cleaners or toasters. Techy instruments and gadgets are so sophisticated, that a cell phone you bought just a couple of years ago is probably 'outdated' in terms of the current capacity and features you now find stocked in the electronics section. Technology moves at lightning speed. While digital cameras have been available for over a decade, the new ones have features no one dreamed of a decade ago.

That digital camera you bought ten years ago may finally need replacement. It's traveled everywhere with you, you've taken thousands and thousands of images and it's finally the worse for wear. The battery casing locking mechanism finally gave out and you're snapping pictures with a large rubber band holding the case together. With a memory card of minuscule proportions, compared to the options available today, you've wisely decided to loosen the purse strings and replace your beloved, but too old digital camera.

You go to your local electronics or camera shop to browse the current goodies. This can be an overwhelming and bewildering experience. Depending on where you look, the sales staff may be well informed or not. In any case, the sales person's job is to sell you a camera. Before you take the leap to invest in a new digital camera, you're well advised to seek out a digital camera buyers guide, if you hope to make an intelligent decision on your purchase.

Where can you find a digital camera buyers guide? Such guides are available both on and offline. Much like consumer reports on cars, appliances, cell phones and yes, toasters, there are digital camera buyers guides which go into great detail on available features, reliability, price for value and comparisons among various manufacturers. Before plunking down some substantial bucks for a pricey camera, you owe it to yourself to know just what you're buying.

Photography magazines often run feature articles of substance, focusing on new developments in the digital camera market. Spending a few bucks on these magazines is well worth the price in bringing you up to date on what's available. Many photography magazines also offer a digital camera buyers guide, with chart comparisons between various brands and models that serve you well in zeroing in on a camera that will perform according to your needs. In addition to the comparison charts, you'll be able to read up on the pros, cons and usefulness of any given feature.

If you take the time to diligently search out every digital camera buyers guide you can find, you'll be much more knowledgeable when you walk into that store or order your new digital camera online. You can walk in confidently, not having to rely on the sales staff. You'll know just the camera you want. Money well spent.

Covert Cameras

By Charlie Reese

I have always liked spy toys, but covert cameras have always been my favorite. There is something about a hidden camera that is just so captivating to anyone who grew up during the Cold War. Nowadays, photographic evidence doesn't mean quite as much as it used to " photos can be convincingly doctored " but there was a time when a picture was the most definite kind of proof you could get.

Covert surveillance cameras were the best weapon of law enforcement to catch dangerous fugitives or intercept spies in the midst of their dirty deeds. A covert camera could be used to bring back nuclear secrets from Russia or provide convincing evidence that a prisoner of war was still alive after being held for months.

Although some of the glamor around covert cameras has died down, the cameras themselves are better than ever. Things which were unthinkable or at least difficult to imagine 20 years ago are now a part of every day reality. You can have cameras the size of a tie pin that can get reasonably good resolution " at least at close range. Slightly larger covert cameras can be smuggled around as lipstick, pens, or flashlights. You could even hide one in your shoe if you wanted to. Even video cameras can be made pretty tiny. I have seen covert cameras small enough to fit on a small radio controlled airplane. With the impressive mini cameras available on the consumer market, who knows what the government can do.

Of course miniaturization isn't everything nowadays. We've proven that we can get covert cameras very small, but sometimes a much more normally sized camera will do quite well. A hidden camera doesn't need to be particularly tiny if you can conceal it properly. Through camouflage, skillful placement, and proper lighting, a fairly large covert camera can go undetected for months or even years.

Even so, to me there is nothing more secure than a covert camera hidden in plain sight. Covert cameras can be disguised as pretty much anything. Your camera could be a pack of cigarettes, your lighter, or even the frame on the side of your glasses. The last one is worthy of consideration because it provides a very convenient way to aim the camera. If you can take a picture just by looking at something, your secret spying is likely to go completely unnoticed. Despite the fact that these secret cameras don't always work as well as in the movies, quite often they give you uncanny good results. It's all a matter of picking out the right gear, positioning it in the right way, and making sure you have the one thing that cameras will always need " light.

Advice of Photographing Wildlife

By SFXsource

Wildlife photography is a very exciting branch of photography, but it requires patience and dedication. It is very easy to become frustrated, but your efforts will be rewarded. Photographers may spend an entire day trying to get one particular shot! These tips are intended to either get you started photographing wildlife, or to inspire you to stick with it. There is a certain awe and beauty about capturing the natural world, particularly animals.

1. The number one tip is to be patient. Easily frustrated, many people will give up, but if you are patient, you may be pleasantly surprised.

2. Don't get too close. It is likely that if you get too close to animals, they will run away. No matter if you are photographing in national parks, jungles, the wilderness, etc., it is of upmost importance to give animals space, and wait for them to come to you if they so choose (animal are very curious).

3. Photograph wildlife in their environment. While it is fun to photograph exotic animals at the zoo, it is more authentic to incorporate where they actually live into the background.

4. Experiment with different shutter speeds. If you photograph a cheetah running with a fast shutter speed, you will freeze the action. On the other hand, with a slow shutter speed, you will get a blurred effect.

5. Occasionally, the wildlife will compose the image for you (this is where it can be good to be patient). If you just look through your lens and observe the animals, you may be surprised and get some unique shots.

6. It will be in your best interest to purchase a zoom lens. Many times it will be hard to get close to wildlife, and a zoom lens gets you closer without putting you in danger and without disturbing the animal.

Don't forget to search for wildlife images by other photographers to give you some inspiration. The work of wildlife photographers can also be found online or in a number of photography magazines.

Now And Then: Photography And The Canon Powershot A590is

By Don Bethune

In 1826, the photograph was taken, and an amazing hobby was born. As much an art as a science, it has changed the way we remember events and report the news. That first picture was taken with a simple sliding box camera and printed on a mixture of silver and chalk that reacted with the light. That was a long time ago, and the advances in film, lenses, and lighting have been great. Cameras were created in many different forms, with different uses and styles. This allowed not only professionals to have their tools, but average users to capture the moments they wanted to preserve.

The earliest cameras were bulky and required the use of what is known as "plates." Made of glass, these plates were smeared with mixtures of salt and chemicals that could capture images when exposed to light. Importantly, these early cameras led to the creation of the camera "shutter," a mechanism which would control the timing of the plates exposure to light, as well as the amount of light permitted to hit the exposure mixture.

The first use of film in photography came in the early 1900s and led to the mass-marketing of cameras later in the century. 35mm film came in a roll and could easily be loaded into a camera for quick and repetitive snapshots. As manufacturing processes improved and competition amongst makers flourished, cameras became cheaper and increasingly compact.

Users praised the creation of the instant camera (remembered most often as a Polaroid) which bypassed the darkroom and created prints on the spot. Film reached its limits, however, and was soon overtaken by the digital camera. With a color display, and free from the tyranny of fragile film, these cameras have made amazing pictures simple and easy. They convert an image into a series of data, called pixels, representing the tiny dots of color you see on your computer screen to make a picture. This data is much easier to store than film, so users can take more pictures.

The software built into cameras now also takes out much of the guesswork. The aim and focus for you. They control the shutter-speed and help you frame the shot. Special modes help you get the photo just right, whether it is a sporting event or a close up of a flower. The detail you can now get in both tight shots and panoramic vistas, day or night, is astonishing. Plus, you can do anything with these photos, from putting them online and sending them to friends, to retouching them on your computer and printing them out.

One of the most popular cameras today is the Canon Powershot A590IS. It is as easy to use as any other point-and-click camera, but it also has all the necessary manual settings to please the skilled photographer. Plus, the 4x optical zoom brings you closer than other cameras, with a clarity that a simple digital zoom can never create.

You canat mess up shots any more with a camera that has 19 shooting modes and 7 scene selections. Plus, you will have no more blurry shots. It comes with an image stabilizer. Most photos taken by amateurs are portraits, and the face detection software keeps the focus on the face, rather than an object in the background or foreground. With the Canon Powershot A590IS youall take pictures people couldnat have dreamed of thirty years ago.

If you get one, be sure to look at the Canon Powershot A590IS manual. Sure, itas simple to use, but you can learn a lot of tips to create even better pictures. Another nice feature comes when you need a new Canon Powershot A590IS battery. You donat need something special or expensive: just two AA batteries.

Photographing The Human Face - Minimizing Wrinkles!

By Dan Eitreim

Your job as a photographer (whether you're an amateur or professional) is simple. You have to make your subjects look as good as they've EVER looked without your tricks and techniques being obvious. That's a task easier said than done.

A number of repairs and improvements can be done in Photoshop, but unless you are a true master at retouching, it's hard to do too much without ruining the portrait. The more problems that you fix "in the camera" the better off you will be and the easier it will be to get seamless retouches.

One big area that can dramatically improve your photos, with very little effort is knowing how to handle acne and wrinkles.

You won't have to do many portrait studies to realize your models all have a few traits in common. Your older subjects want to look younger, even if they don't say they do, and younger subjects want to minimize their acne.

Adults. The deeper and darker our wrinkles, the older we look. It happens to all of us eventually. If we can lighten or even eliminate our wrinkles, we look younger. Fortunately, this is a problem that is easy to fix.

Let's first examine - What is a wrinkle? it's a small crevice, defined visually by the shadow at the bottom. The older we get, the deeper the wrinkle, the darker the shadow. It's a 1-2-3 progression. The darker the shadow, the older we appear to be. So, how do we take years off our models?

Easy, lighten the shadow!

If you have light that is glancing across the face from above or to the side of the subject, the deepest part of the wrinkle crevices are not getting any light and appear darker. This makes our model look older. Depending on the directionality and intensity of the light, this can add a lot of "visual" years to our subject.

Try to avoid glancing side light and have the light focused directly into the face. The direct light will be able to work it's way into the wrinkles, filling them with light. This will make your model appear much younger. AND save you some time and effort in Photoshop.

Acne? Use the same cure. Acne scars, pimples and other facial blemishes are at least partially defined by the shadows they cast on the face. Again, light skimming the face from the side will cast longer and harder shadows thus making the acne scars more pronounced and pimples appear larger. Shine your light directly into the face and they will be minimized or disappear altogether.

Use a reflector of some sort or even your on camera flash in addition to the sun to fill in the shadows. Your smooth faced teens and wrinkle free adults will thank you.

You now know as much as most professionals! Now it's time to make some money with YOUR camera! to see how easy this is, follow one of the links to my site...

Master Photographic Lighting

By Dan Eitreim

Learning photo lighting is pretty easy. Though the true test of good photography lies in making your subjects look their best, this is accomplished by using the correct lighting for their faces.

Obviously you won't want to be spending all your free time in Photoshop, it would kill your profit margins.

So...If lighting is your main concern and you are spending too much time in Photoshop trying to "fix" your photos, you are going to have to learn some lighting control techniques. Here are some thoughts.

Instead of just hit or miss shooting, first you'll need to learn the foundations of light. Here are a few of the basic patterns.

Narrow light, Broad light, Split light, Butterfly, Renaissance, Closed Loop, Open loop

A couple hours in the photo section of the local library should do to define what these are. Make notes. Each pattern is the best one for certain faces and artistic effects. You need them all in your bag of tricks.

Now, go home and - leaving your camera in the bag - let's do some experimenting.

Grab a couple of kids - use your own or bribe the neighbor's kids - and have them sitting on a chair in a darkened room. Now, with a flashlight as your only source of light, learn where the light has to be positioned - in relation to the face - to create each of the patterns. Draw diagrams and make notes in a notebook you can stick in your camera bag and always have with you.

Right now, we are concerned with the angle of the light and shadows. Not the color or intensity.

Once you know the proper angles to create the lighting patterns, then start playing with intensity. Bring your flashlight closer to your model, then further away. Note the affect on the intensity of the highlights and shadows.

Next, try diffusing the light by covering it with a piece of tracing paper. See what that does to the shadows?

Next, have one of the kids hold the flashlight in place - we'll call this the main light - and add a second flashlight at camera position. We'll call this one the fill light. Now create one of the patterns. i.e. the closed loop - which is the same as Renaissance by the way. What happened to the shadows when you added the second light? What happens if you move it to a different position? What does it do to the shadows to move closer? Further away?

What about the background? Move your model closer and further away from the wall. What happens to the background with one light? How about two? Do the shadows change?

One afternoon with a couple flashlights and a cooperative model should answer most of your questions as to what to do to fix your lighting/shadow issues.

Once we are comfortable with the patterns and how to create them, all we have to do is make them on location.

Let's make the sun our main light. Practice positioning your model at various angles to the sun - to learn how to create the same patterns you were making before. To get the angles, intensity and color of light you want, you may have to adjust the time of day for your experimentation.

If the look you are after calls for 1 diffused light, (remember our tracing paper experiments?) position a diffusion screen of some sort between your model and the sun.

You may want to wait for a cloud to come by, use the shade of a porch or a tree or, if you are feeling high tech, use a large piece of translucent material.

If your look calls for a main light and a fill, use the sun (diffused or not, as needed) as your main light and your camera's flash as the fill. You can tape some tracing paper over it for diffusion. Two layers for more diffusion, etc. You could also use a commercially made translucent plastic flash diffuser.

Lighting can be quickly and easily learned and the results are worth the effort.

You now know more about lighting than half the professionals out there. To learn how YOU can make money (a lot of money) with your camera follow the links in my resources file...

Best digital camera today - Nikon Coolpix P90

By Dick Busch

For many people the whole idea of buying a digital camera is confusing with so many to choose from. Finding the best digital camera should really be quite simple with all the consumer reports and comparisons available both online and in written periodicals. Eventually saving enough money to buy that eye-popping, 12 megapixel, 24x optical zoom with up to a sixteen gigabyte expandable memory using super hi-speed SD memory card and of course, very compact; which we hope be the envy of almost everyone we know. The problem is by the time you actually get to the mall, the model you have set your heart on is no longer the one to own as there is a new better version that you must now have.

We sigh because the manufacturer of this amazing gadget claims that this is the best digital camera yet out in the market. But this dilemma is very short lived because you promised yourself the best digital camera and that is what you are going to have. Don't worry though if you are not sure what to do; just follow the guide below and you shouldn't go to far wrong. First off try and search out a model with a higher number of pixels, referred to megapixels; you ideally need over 5 although with today's cameras it would be hard to find one under that anyway.

A quick tip on this subject involves the batteries which have a tendency to run out quicker if a large LCD screen is fitted and is used constantly; some sound advice is carry spares! A digital camera with an optical zoom facility is the one to try for and a digital zoom only camera should be avoided if you want clear, well defined images. Unfortunately digital zooms just don't cut it so avoid them unless you are buying an inexpensive camera as a gift for a child. As there are so many types of storage card available you will have to ensure you buy the correct one.

Now we are told that this latest model is in fact the best digital camera; we have no choice but to pay the extra and have that one instead. But this dilemma is very short lived because you promised yourself the best digital camera and that is what you are going to have. If you are new to digital cameras and photography the tips below might be useful and point you in the right direction. First off try and search out a model with a higher number of pixels, referred to megapixels; you ideally need over 5 although with today's cameras it would be hard to find one under that anyway.

Generally speaking the higher the mega pixels, the better the actual photograph will come out where a mega pixel is equivalent to one million pixels. Superior color definition and the chance to print off larger than normal images are usually the main reasons for buying a model with high megapixel resolution. LCD screens have over the years become much larger which means you can frame your shot easier and view the result with more ease than ever before. The best digital cameras are able to touch up and edit the images this is an excellent feature to have as standard.

The only downside to this great feature is it uses more battery power so always keep a fresh set with you at all times if you don't want to be caught out. More and more digital cameras are coming equipped with an optical zoom and this is the sort to try for even if it is only a three times power. Low spec cameras that only cost a fraction for their quality cousins will only have a digital zoom; unless you really aren't at all fussy about your shots you would be well advised to stay clear of buying a digital zoom only camera. As there are so many types of storage card available you will have to ensure you buy the correct one.

Memory cards are used in all sorts of electronic gadgets and you may already have heard of the main ones: Sony's Memory Stick, compact Flash, Secure Digital and XD cards for example. Fortunately the price for digital memory seem to fall in line with the size of cameras resolution increases so buy the largest you can affords and that is compatible with your version. The cost has dropped rapidly so take advantage of these larger storage capacity cards now that the price is lower. After all is said and done, the best digital camera you choose should match your lifestyle as much as it should your pocket. either you use your camera for fun or for serious photography, as long as it is used it will be worth the financial outlay.

Create Realistic Imagery with the Canon PowerShot A1000IS

By Matt Ryan

Canons PowerShot cameras have been impressing consumers for years. The PowerShot A1000IS will be no different. With many of the same features, some new features, a sleek design, and a low sticker price - the A1000IS is possibly the camera purchase of the year. The A1000IS is much smaller than its predecessors, yet offers a zoom lens that has never been offered on a compact point-and-shoot camera. The A1000IS will give consumers vivid pictures for all occasions.

This 10-megapixel point-and-shoot camera has a 4x optical zoom lens with a focal length of 35-140mm. Canon did an impeccable job implementing this type of lens on such a compact piece of equipment, and kept a fairly elegant appearance as well.

The 2.5-inch TFT color LCD display provides consumers with an extremely realistic review of their videos and stills. Some features of the A1000 are an optical viewfinder (new for the PowerShot cameras), DIGIC III processor, numerous different shooting modes, face detection, red eye correction, and more. The optical imager stabilizer, for example, works to eliminate the blur caused by hand, lens, or camera shake.

There are 17 different shooting modes offered on the PowerShot A1000IS. These modes make it easier to capture those spontaneous moments without having to worry about adjusting settings for proper exposure. Easy and auto mode are the best for your every day pictures. ISO 3200 offers amazing setting, and outcomes, for scenes that are not well lit, yet you cannot use a flash.

The DIGIC III image processor not only helps with power management, but also is the brains behind the operation of vivid imagery. Face detection technology would not provide such precise settings - focus, exposure, flash - without it. Power management features allow you to continue taking pictures longer than many other cameras would allow. The Red Eye Reduction has improved with DIGIC III, as the camera works to remove red eye prior to storing the image.

Face detection also offers an added bonus. Consumers can select a particular subject, or face, in a given shot. The camera will automatically focus on that face, even as it moves around in the frame.

Motion detection technology is great for capturing children and animals. This feature detects movement and adjusts settings appropriately to reduce blur. Typically, the ISO settings are adjusted, but this saves you from having to manually change the settings and risk losing the picture.

Upon purchasing a PowerShot A1000IS, you will receive two AA batteries, SD memory card (32MB), wrist strap, USB cable, AV cable, and the necessary software. There is no need to make additional purchases to begin using your new camera. The wrist strap will be needed as there is no longer a rubberized grip on the camera; if you hand gets sweaty it could easily slip away.

With the A1000IS, you will get durability and dependability. You can even choose between four colors, purple, silver, brown, and blue. The A1000IS also has an appealing price tag at $149. If you are looking for a point-and-shoot camera that produces exceptionally crisp images, the Cannon PowerShot A1000IS is worth looking at.

The A590is- Canon's Digital Camera

By Don Bethune

Digital cameras are just like normal cameras but with more features that make digital cameras easier to use. With just a quick skim through the owners manual, combined with having a few knowledgeable friends, you can quickly begin to take great pictures. One of the biggest differences is that, unlike regular film cameras, you can immediately see the pictures you take with a digital camera.

Based on a combination of the features and cost of the camera, the Canon A590is is the best camera on the market. Here are some of the features that makes the camera great: a 2.5" LCD screen, face detection technology, the New Easy Mode, 4x optical image-stabilized zoom. Images are captured to a SD card and the camera uses AA batteries. Best of all, despite its low price, the camera has 8.0-megapixels.

The SD card that the camera captures images to is not included, although you can pick one up for $20-60. The cards come in different sizes, which refers to the amount of memory space, not the actual size of the card.

The new easy mode allows you to start taking pictures without reading the owner's manual. The camera takes care of the settings, allowing you to take beautiful pictures without needing any additional expertise. This makes the camera perfect for novices.

With the 4x optical zoom, the camera is able to take close-ups, even from a far away distance. And because of the 8-megapixels, you won't always need to zoom, and your close ups will still come out beautiful and clear

Due to the camera len's motion detection technology, your pictures will always come out clear. The camera will make changes in its settings, based on how fast the subject is moving, so what you see is exactly that will come out.

Two other key features of the camera are red-eye correction and face detection. The red-eye correction mode will prevent red-eyes to appear in your subjects' eyes. You can also go back to other pictures and take the red-eyes out. With face detection, you can be sure the faces you are taking a picture of come out clear, because your camera will focus on it.

All of the reviews for the Canon590is have been positive, because of the combination of low price and great features. This camera will appears to all those who want an easy way to take lasting pictures and those who don't want spend their savings on a complicated camera.

A Digital Photographer's Essential Accessory? Storage Cards!

By Sylvia Howard

While old style cameras required photographic film, modern digital cameras necessitate memory cards as their most important accessory. The memory that is inbuilt in most cameras in only enough for a tiny number of photos, so you will need one or more storage cards at all costs.

Don't stop at getting a single memory card for your digital camera, though. There are several reasons why you should get more than just one. For starters, digital camera memory cards are cheap and don't take up any space, and having several will greatly improve your chances to take more and better pictures.

If you are about to take a vacation in remote places where you will be unable to transfer the images, and with no shops readily available in the vicinity, you will quickly appreciate the freedom of not having to ration your pictures.

In fact not having to think twice every time that you press the shutter will turn you into a bolder photographer. You will find that several risky pictures and framings give great results, which is why digital camera memory cards will make you a more experienced and ultimately better photographer.

Also, most digital cameras have a setting that will allow you to take three simultaneous pictures of the same subject - one slightly underexposed and another overexposed - and here also you will be able to choose the best one.

Imagine being in a remote location and being able to take a daily average of two hundred of pictures of interesting subjects, and not of twenty. Would that make a difference on the way that you photograph?

Extra digital camera memory cards will also diminish the risk that you will fill up the available storage and that you will have to delete great pictures to make space for new ones.

So as you can see, there are several reasons why extra digital camera memory cards as accessories is a sensible proposition. When you buy them, be especially attentive to getting the ones that are the right format for your camera, there are several manufacturers and not all storage cards are compatible across cameras.

Regarding the amount of memory, nowadays storage cards range from one to 32 GB and more. You should take as much memory as you may need and then some more, spread over two or three cards for redundancy.

Also, if you are going with multiple memory cards as part of your digital camera accessories, you should also consider a card reader, which will allow you to seamlessly transfer your pictures from the card to a PC, or even directly to a digital photo printer, via a USB connection.

De-Multiplexing To The Max: 640 Gbits/Second

De-Multiplexing To The Max: 640 Gbits/Second

February 2, 2009

Washington — Sliced light is how we communicate now. Millions of phone calls and cable television shows per second are dispatched through fibers in the form of digital zeros and ones formed by chopping laser pulses into bits. This slicing and dicing is generally done with an electro-optic modulator, a device for allowing an electric signal to switch a laser beam on and off at high speeds (the equivalent of putting your hand in front of a flashlight). Reading that fast data stream with a compact and reliable receiver is another matter. A new error-free speed-reading record using a compact ultra-fast component—640 Gbits/second (Gbps, or billion bits per second)—has now been established by a collaboration of scientists from Denmark and Australia, who report their results in the journal Optics Express, the Optical Society's (OSA) open-access journal.

New technology and new ways of doing business require new approaches to old procedures. Conventional readers of optical data depend on photo-detectors, electronic devices that can operate up to approximately 40 Gbps. This in itself represents a great feat of rapid reading, but it's not good enough for the higher-rate data streams being designed now. The data receiving rate has to keep up.

Sometimes to speed up data transmission several signals are multiplexed: each, with its own stream of coded data, is sent down an optical fiber at the same time. In other words, 10 parallel streams of data could each be sent at a rate of 10 Gbps and then added up to an effective stream of 100 Gbps. At the receiving end the parallel signals have to be read out in a complementary de-multiplexing process. Reliable and fast multiplexing and de-multiplexing represent a major bottleneck in linking up the electronic and photonic worlds.

In 1998 researchers in Japan created a data stream as high as 640 Gbps and were able to read it back, but the read-out apparatus relied on long lengths of special optical fiber. This particular approach is somewhat unstable. The new de-multiplexing device demonstrated at the Technical University of Denmark, by contrast, can handle the high data rate, and can do so in a stable manner. Furthermore, instead of fibers 50 meters long, they accomplish their de-multiplexing of the data stream with a waveguide only 5 cm long, an innovation developed at the Centre for Ultrahigh Bandwidth Devices for Optical Systems, or CUDOS, in Australia. Another benefit of the new device with the compact size is the potential for integration with other components to create more advanced ultra-fast functional chips. The dynamics involved in the CUDOS device could even allow for still higher data rates approaching terabits/second (Tbps, or trillion bits per second).

One of the authors of the new report, Danish scientist Leif K. Oxenløwe, says that the record speeds of de-multiplexing represented by his tiny glass microchip is a boon to circuit designers and opens the door to faster network speeds. In the near future, the Danish and Australian researchers hope to achieve 1 Tbps Ethernet capability.

Canon EOS 50D - New and Improved Canon EOS 40D

By Matt Ryan

Canon - known for their quality products - has released another amazing camera - the EOS 50D. Like all of their cameras, this model improves upon any of the missing features or flaws in earlier models. If you liked the 40D, you will love the 50D as it is packed with everything a photographer could need.

Like most Canon cameras, the EOS 50D is for higher end photographers, not beginners. The functions and features, on the 50D, would go to waste with the type of photography done by amateurs and beginners. This is not to say they cannot use the camera, it just might be a bit overwhelming and expensive for their needs.

Its 15.1-megapixel CMOS sensor greatly improves upon the range of ISO settings. ISO settings, on the EOS 50D range from 100 to 3,200. With added features and ISO presets, consumers can expand ISO up to 6,400 or even 12,800.

Some features present in the 50D that were nonexistent in the 40D, are vignette correction, Automatic Lighting Optimizer with three levels, adjustable noise reduction, a Creative Auto mode, a lens micro adjustment function, and face detection autofocus in Live View mode.

The Canon also includes features such as 6.3fps continuous shooting, DIGIC 4 processor, 9-point wide area AF, EOS Integrated Cleaning System, HDMI connectivity, and full compatibility with EF, EF-S, and EX-series Speedlites lenses. Overall performance, on the 50D, is amazing with the integration of the DIGIC 4 processor. This technology also increases the overall resolution of images.

There is a 3.0" Clear View VGA LCD display on the EOS 50D. Live View mode and Face Detection Live AF have been tightly integrated, into the display, to make for a more realistic experience. The LCD screen displays images at a 920,000-dot resolution - experience pure vibrancy. The screen is protected, with a protective coating, from fingerprints, dirt, glare, and scratches.

With measurements of 5.7 x 4.2 x 2.9-inches, and weighing in just under two pounds, the EOS 50D fits comfortably in your hands. Buttons, menus, and different functions are easily accessible with its ergonomic design. (The weight will vary based on the lens that you have attached to the camera; weight shown here is with no lens attached.)

The Canon EOS 50D can be purchased for around $1,399. If you are a smart shopper, and good at finding deals, you can easily purchase this model for a couple hundred less than what is shown here. Kits, which include different lenses, are sold for much higher prices. These kits are usually sold to professional photographers, as they need advanced lenses.

Canons EOS 50D is very similar to the 40D. If you have had any experience with the 40D, handling the 50D will almost feel like the same camera. With the exception of additional features and more advanced technology integration. Otherwise, the overall design, build, and output are of the utmost quality. Photographers alike can capture true-color realistic pictures every time they click the shutter button.

Professional or Everyday Photos, the Lumix DMC-LX3 is the Answer

By Matt Ryan

Panasonic has introduced a new product to their Lumix family - the Lumix DMC-LX3. This camera gives consumers the convenience of a point-and-shoot with professional grade functions and images. Regardless of your photography level of expertise, the Lumix DMC-LX3 is a grand addition to your camera collection.

The DMC-LX3 is a 10.1-megapixel camera. It has a 2.5x optical zoom along with features such as Optical Image Stabilization, Intelligent Auto Mode, RAW support, ISO 80-1600, and more. Even though it only measures in at 2.34 x 4.28 x 1.06-inches, it still encompasses a nice sized display. The 3.0-inch LCD display allows consumers to view images - immediately - at a 460,000-dot resolution.

Auto face detection (also known as AF) is common in cameras today; however, the AF on the LX3 can detect up to 15 faces in one frame. The combination of AF and autofocus tracking make for exceptionally focused and exposed images. This model automatically focuses on moving objects along with setting proper exposure for the perfect image.

ISO settings, on the LX3, start at 80 and can be extended up to 6,400 (with High Sensitivity Auto mode). Panasonic has incorporated 24 preset shooting modes into the LX3. This eliminates consumers from having to manually adjust ISO settings. (ISO settings are to be adjust low and high based on natural light provided in a given shot.) With numerous presets there is no need for consumers to worry about proper ISO settings. For professional photographers; however, you can manually adjust aperture and shutter-priority modes.

The DMC-LX3 also allows consumers to record high-def video with sound. At a 1,280 x 720 resolution, you will only be able to record 24fps. However, adjusting the resolution to a lower setting will allow consumers to capture up to 30fps.

The Lumix DMC-LX3 comes with 50MB of internal storage, which typically is not enough for the avid photographer. It also accepts SD/SDHC and Multimedia cards. SD/SDHC memory cards typically work better with the LX3.

Transferring files is easy with the use of the USB 2.0 port. You could also view your files directly on your television with the use of the NTSC video output or high-def component video output. All of these connectivity ports are easily accessible and for your convenience.

Panasonic has kept the same body style for all of their LX models; this makes transitions between cameras seamless for consumers - after all - why fix it if it isn't broken. The body shape makes it fit comfortably in any size hand, and button locations allow consumers to effortlessly access different functions and actions. Additional options or settings are available via the LCD screen.

The Lumix DMC-LX3 is one of the most durable point-and-shoot cameras on the market - with its metal body, port doors, and firm buttons. It is safe to travel with and take to nearly any crazy event you want to photograph. Kids can even play with the LX3 without too much concern of them breaking it.

Panasonic has outdone themselves once again with the release of the Lumix DMC-LX3. They have provided photographers - of any level - with a functionally easy to use point-and-shoot camera. For only $500 you easily fit this model into your budget.

By Matt Ryan

Fujifilm is known for their creatively designed handheld cameras, and their newest model - the FinePix z20fd - definitely fits the bill. This compact camera fits comfortably, in the palm of your hand, and provides all of the necessary functionality you will need in a camera.

The FinePix z20fd is a pocket sized camera with measurements of only 3.6 x 2.2 x 0.8 inches. Additionally, it only weighs 4.4 ounces. The combination of size and weight make this camera compact enough that just about anyone can comfortably operate it with the use of one hand. For those of you who like a little spice, you can choose from a red, green, pink, blue, or even black exterior.

This is a 10-megapixel camera with a 3x optical zoom. With just these features, and no added bonuses, you can produce images with 3,648 x 2,736 pixels, which is great for any picture frame - digital or printed. There is an additional 5.6x digital zoom; however, these zooms are known to cause distortion in photos.

Automatic exposure control is one of many features on the FinePix z20fd. This feature allows consumers to snap pictures with little to no modifications to other settings. Many additional features on this model, which make it even more appealing to the average consumer.

Other features include preset shooting modes, face detection with or without red eye removal, photo stabilization, IrSimple, blog mode, white balance, ISO settings, and even color modes. Features that can easily be adjusted manually would be the ISO settings, color modes, and white balance adjustments. Again, this really should not be necessary with the automatic exposure control.

Not so Secret Digital Photography Tricks

By Russell Roberds

Have you ever desired to improve your photo taking skill, yet did not know where to to start? Well, what if I told you that in just a few minutes, you could be using some fantastic digital photography tricks that will take your photos from okay to incredible!

If you are anything like me, you have thrown away a lot of time and some cases a lot of money taking photographs, that are, well, not that great. After several years (too many to reveal), I finally decided to do something about it. I read a couple of books, magazines and took a couple of classes to advance my digital photography skills. What I learned is that there are a tremendous amount of digital photography tricks that are so easy, I picked them up in nothing flat and discovered sensational results.

I will not pledge that you will be a superstar from these digital photography tricks, but you will identify results from your very first picture.

1. Fill the frame: One of the most basic digital photography tricks to grasp, but harder to put into practice. When you shoot a picture, how small is your subject in the view finder? When I look at old pictures I took, the subject invariably seemed to be tiny. Well, by filling the frame you highlight the object better. Also, whenever the subject takes up most or the entire frame, you are "removing" objects from the picture that might have appeared beside or around the subject. By getting rid of the "clutter", the viewer then focuses more on your subject. The practice that I now put to work is if you conclude you are close enough, your not. If you conclude you are too close, then you are probably the perfect distance, so take the picture.

2. Would you repeat that?: An easy to grasp digital photography trick is repetition. Repeating arrangements, colors or textures make fabulous photos! You can find many repeating patterns in nature. One way to enhance a pattern picture is to find a pattern and then an object that defies the pattern, like a carton full of red apples with one yellow one. The odd man out pulls the viewer's eye into the picture and moreover composes a contradiction.

3. One of the digital photography tricks used in many pictures is reflection: The earth is chock-full of reflective objects and faces; water, glass, chrome, waxed cars and mirrors to mention a few. They alter our natural awareness by twisting the original. Whenever you take a photo of the reflection rather than the original, it will engage increased interest to your photo.

4. Last yet not the least of the digital photography tricks is to construct a frame within the frame. I am not saying a photo frame, I am talking about generating a frame encompassing your principal object using objects in the area around your subject. One idea is to locate yourself on one side of a door frame and your subject on the opposite side. Shoot the photo so that the door frame is around the edges of the view finder. The picture will pull the viewers eye to the interior of the frame and to your subject. It may also construct extra depth in the photo.

These are a few of the simple techniques that skillful photographers put to use to attain those awesome photos in magazines, books and on the web. My desire is that you will employ these digital photography tricks to enhance your picture taking talent. Happy shooting and say cheese (make mine white American)
