Digital Photography - How To Learn Photography

By Carol Bell

Have you seen an attractive digital image and wanted to find out how to provide similar results? Perhaps you are simply bored with your conventional camera and are prepared to make the jump into the digital age by buying your first digicam. No matter what your reason, it's not tough to learn digital photography and the way to employ an electronic camera. The options applying to on-line courses, authorization programs, university classes, and one on one instructions are basically endless!

There are so many different locations where you can learn digital photography. Most local colleges, especially the art institutes, offer both one-time courses and degree programs. Online colleges usually offer these options as well. Some colleges even offer professional certification programs. These options are best for the more serious students.

If the will to learn digital photography is related to a hobby vs a vocation option, you might consider other options. For example, many public college systems and county bodies offer short, 8 week long courses pertaining to a wide selection of topics including digital photography. You may also find tips, strategies, and instructions in books and even on the internet! The Net provides a plethora of resources,e.g. free on-line help files.

You can establish the learning methodology that's best for you by asking of yourself what your goals are. Are you targeting to get to the pro level, or do you simply wish to learn digital photography so you can use your digicam during family and community events? If you'd like to become a pro snapper, your best chance could be to gain documentation in a web course, or earn your degree at a local university. However, if you need to gain understanding of basic abilities when you learn digital photography, you may consider an one off tutorial or a self teaching book.

You must also consider what your availability is, and what proportion of your time you are ready to give to learn digital photography. If you are ready to devote lots of time to the topic, you've got more options open to you. If your schedule is less flexible, then you'll be at the beck and call of course schedules and available time slots.

If you are dedicated to learning digital photography, then there's no reason why one of these options would not work for you. All you have to do to learn digital photography is identify your purpose and availability, and then you're prepared to head off to the pinnacle of the class!

What You Need To Know About Red Light Traffic Cameras

By Marcus Adams

Red light cameras are becoming increasingly popular throughout the United States as the country continues to grow in population. Legislative bodies across the nation will tell you that the purpose of these cameras is to create an easier and more effective way to enforce the rules of the road. Red light cameras are used to help police departments enforce red light laws at major, sometimes even, extremely dangerous intersections without having to place an officer at the scene. However, we are not getting the real story.

Lets take a look at the technology behind the red light camera. Red light cameras take photographs of vehicles that supposedly disobey red light laws. Those photographs are sent to the local police department for analysis and processing and the photo is mailed to the vehicle owner with a ticket. The photo generally has the front of the car, sometimes the backend, with the driver's face in the windshield and the license plate visible.

Usually there is not a mandatory court date listed on the ticket, you can pay the fine and mail it to the courthouse. You can however fight the ticket in court if you so choose. Reasons for fighting a ticket of this nature could be that you were not driving the car and it was another driver. They send the ticket to the person who the vehicle is registered to, not the driver, since the camera cannot identify the driver.

Perhaps the best reason to fight a red light ticket is because no violation occurred at all. There has been an alarming increase in red light tickets issued incorrectly. Just recently a friend of mine was issued a ticket for making a legal right turn on red. He has the option to appear in court to fight the ticket, or pay the $100 fine by mail. If he decides to go to court and fight the ticket he will miss at least a half day of work. Either way he loses in a situation where no actual violation occurred.

There has increasing opposition to the use of red light cameras since they were placed into service over the last few years. In addition to my friends situation, another one of those oppositions was that some jurisdictions were illegally changing the timing of the yellow light. This means that the yellow light would change at a quicker rate to red than it is legally allowed to. This resulted in more revenue for those jurisdictions. A case in Tennessee awarded supposed violators a refund of over $8,000 total in fines paid to the state because of illegally changed timing on the yellow lights there. There is no hard evidence as to whether or not these red light cameras have reduced the number of accidents or actually caused more because people are slamming on their brakes to avoid a ticket.

These types of situations beg the question. Are red light cameras really there to make the roads safer? I would argue that the main purpose is to raise additional revenue to help our elected officials collect and spend more of our hard earned money in a faltering economy. This type of enforcement is actually a hidden tax.

Fortunately, we now have a defense against this hidden tax. You can protect yourself from these red light cameras. Please realize that I am not endorsing illegal driving activities, but a way to protect yourself and your rights as a safe, law abiding driver.

Choosing an Infrared Security Camera

By Chad Buie

Darkness is the enemy of security system setups. Unless you have an infrared security camera, as infrared security cameras excel at capturing video in the dark.

Although most security consultants are familiar with an infrared security cameras single drawback: the capture in black and white, many new security personnel do not understand the advantages of using an infrared security camera or when to use one in a security setup.

Simply put, black and white video is better than no video and there are many situations where traditional cameras cannot capture anything.

A good security consultant will understand that there are often variables that will be outside of your control. Configuring a CCTV setup, has to plan for the unexpected such as a key light burning out, getting shattered, or having their power cut. Installing a infrared security camera functions as a tremendous failsafe for these conditions. Also, many times it is more economical, considerate, discrete, or otherwise preferred to use infrared security cameras outdoors rather than flood lighting.

Infrared security cameras measure infrared radiation (or IR). Infrared radiation sensors are often called heat sensors, as they are used in heat seeking missiles and night vision goggles. But this is a misconception as heat is felt from more than just infrared spectrum and the infrared spectrum contains more than heat (for example, your television remote uses an infrared sensor and infrared light, but does not get hot when you use it). For purposes of security systems, however, we will be primarily concerned with the infrared sensor picking up heat signatures of human bodies.

Infrared cameras come with many different numbers of infrared lights built into the lens. Some have as many as 64 or as few as 6 bulbs, but the number of bulbs is not the only thing to consider. The size of the infrared bulb is important as well. Generally the more infrared light, in both size and number, that a infrared security camera has the farther that you will be able to see with the camera.

When it comes infrared cameras if the cameras has 12 or more bulbs, it was not meant to be used indoors. This is because many flat glossy surfaces can reflect the light back and overwhelm the sensors. A few examples of these types of surfaces include windows, doors, coffee tables, even walls painted with "glossy" paint finishes can wash out an infrared sensor if it has too much light. It is better to know where you will install the camera rather than just assuming that more lights equal a better picture.

When to use an Infrared Security Camera in your Security System Setup

By Chad Buie

If you need to capture security video in the dark, you need an infrared security camera. Infrared security cameras have advantages and disadvantages that must be considered when designing a security system.

Let's start out by acknowledging a infrared security camera's obvious drawback: they capture black and white video. With that said, we can begin to speak about the benefits of having an infrared security camera in your security setup and the different types of infrared cameras.

An infrared security camera has the ability to capture video in conditions where other cameras cannot capture anything. Faced between having black and white video is better than having none.

Many closed caption television security system cameras hinge on having good available lighting. Often times this means that a thousand dollar setup can many times be rendered useless and ineffective by simply removing the light source, by either destroying or disabling the light. In this situation a infrared security camera would make an excellent failsafe. Secondly, many times the lighting necessary to properly secure an outside location would be overwhelming to nearby residents or businesses, draw unwelcome attention, or otherwise be undesirable. This is another situation where a infrared security camera would be very beneficial.

How do Infrared security cameras work? Infrared Sensors (or IR) detect infrared radiation, which is essentially the byproduct of heat. Specifically, electromagnetic radiation has a wavelength longer than visible light but shorter than a microwave, which means that people cannot see it or be damaged by it. Infrared (or thermal) imaging is used in many devises such as smart missiles, night vision goggles, and television remotes. Other scientific uses involve using infrared light to predict the weather or study the formation of stars. Obviously, visible light is not necessary to produce heat, which is why infrared cameras work so well at night.

Infrared cameras come with many different numbers of infrared lights built into the lens. Some have as many as 64 or as few as 6 bulbs, but the number of bulbs is not the only thing to consider. The size of the infrared bulb is important as well. Generally the more infrared light, in both size and number, that a infrared security camera has the farther that you will be able to see with the camera.

Video surveillance systems can be used in many instances and they provide an accurate record of activity going on under their watch. Video surveillance is a great idea for a business owner who is not at their business at all times of the day to watch what is going on in their business during the hours when they are open.

As of today, the cameras not only take photos but also videos with varying depth, resolution and image size. To our great surprise, there are already underwater cameras that are perfect for water memories. This has completely revolutionized the technology and by far extends its usual limitations.

Since the initial launch of a company to publicize its own underwater camera, camera giants and several colleagues made their own brands as well. For each year, countless underwater cameras have been added, changed or improved making a new mark for each. In fact, if you do a Google search for a specific camera, including the waterproof ones, it will issue over a million hits and hundreds of brands. With this, it occurred to me to give you an initial resolution to solve consumer dilemma and make your choosing much easier. Let me give you the top three underwater cameras and what they can do and what they have.

First on our list would be the SeaLife DC1000. This brand has carved its niche in underwater photography and since then has been setting high standards specifically dedicated to water-based gadgets.

Digital Camera Binoculars Best Of Both Worlds

By Riz Goodman

The big burden of carrying all the things on a hunting expedition can be a pain and that is why it is better to have a few things combined. One such thing is the digital camera binoculars. These are the binoculars as well as the digital camera combined. This helps as you can easily click a picture of the object that you are about to hunt. In fact another major thing that is going to happen here is the fact that you have that special video camera feature built in for instant replay which helps in capturing the video footage easily.

There are a couple of things that you should know when you are selecting the binoculars with an in built digital camera. The first and foremost thing that you should be worried about is the resolution. Now be aware that this resolution will be different than the resolution of the binoculars. Always go for more 1 mega pixel resolution. Also check if the binoculars have the play back facility of small videos. A lot of binoculars come with the instant replay feature.

The digital cameras generally have a memory which is not capable of storing many pictures and it would be better to have some sort of the external memory and the best thing to do in that case is that to buy external memory. The way to buy external memory is to buy the SD memory card.

The general view is that binoculars with digital cameras are not that worth the price but with recent technological advancements all good manufacturers have come up with a variety of better features and styles.

It is generally a very good practice to go into a nearby binocular retailer shop and check the quality of the binoculars and also check how it adjusts in your hand. These binoculars are very heavy and need a good grip.

Make sure that if you are a photo enthusiast then you should go only with digital camera binoculars.

What You Should Know Before Buying a Digital Camera

By Daniel Henderlei

The key technical component of digital photography is the semiconductor. Light is focused onto a semiconductor, creating a digital image. Digital images have let us enter a new paperless age of photography as images can be stored on computers instead of printed.

Talk to those you know who own digital cameras before buying one. Friends and family can offer the best advice, and tell you which brands and models they favor or are disinclined towards. You can make a sound purchase when combining their experience with what you read on the Internet.

For nature lovers who take photos of the great outdoors, a large zoom lens is very helpful. For those of you want to shoot photos of their kids involved in an activity, a fast response time is key, as children move around quickly. For set photos where family and friends are posing, you'll probably want a model that takes pictures in dim light.

For digital cameras, you've got the Point-and-Shoot and the Digital SLR. If you're a novice stick a simple model that's well-rounded - resist the temptation to splurge your money on a super-advanced camera, because you'll be paying for a lot that you'll never use. By the time you learn to use it, you'll probably be wanting another camera with even more cool features.

The Point-and-Shoot camera

Beginners will like the point-and-shoot. It lives up to its name as most settings are automatic, and will adjust itself for you based on the environment and lighting. Customization can still be available as many cameras offer presets for environments like sunny, outdoors, indoors, etc.

Use automatic settings when you want the light sensitivity (ISO) and focal length calculated for you. Read around to find which cameras are best at this.

The Compact is slim, and ranges in size from pocket cameras to ones than fit in a purse. Most compacts have wide-angle and zoom lenses, blur reduction, image stabilization, scene mode pre-sets, and face detection. They can also have LCD displays that are large despite the smallness of the camera.

For distant subjects, check out Optical Zoom cameras. They capture small details, and can crop a scene easily. Optical Zooms have a feature where the camera lens is physically adjusted to improve image quality, with a natural-looking image. Digital Zoom crops the image and then enlarges it to fill the frame - this affects the quality and clarity of the image. Cropping can also be done easily on your PC.

Digital SLR Cameras (Single Lens Reflex)

Digital SLR cameras are for advanced users - those who want to manage and control what the camera does, rather than just point and shoot. SLRs can offer interchangeable lenses, and have a myriad of manual controls. Many settings can still be automatic, but an SLR is best for those who want hands-on control instead of automatic settings.

Digital Camera Lens

By Scott Paul

Canon new lenses are also exceptional. Canon's Digital Rebel was a market success, and the company's new Rebel XT is also hitting good reviews. The previous camera was 6.3 megapixels, the new one is 8.0 and it's a little smaller as well.

While digital SLR cameras are extremely popular among professional photographers, some consumers have shied away from them because they are larger than compact digital cameras and some models can be complicated to the uninitiated user.

Canon fixed everything that needed to be fixed. Except they really dropped the ball on the viewfinder. Canon provides a dust compensation feature in the XTi's free software. You shoot a blank image as a reference. Canon touts its smaller, lighter body as well; it's nearly as small as you can get in a digital SLR.

But while that might appeal to the small handed and nimble, the XT's compressed, lightweight, and slightly chintzy-feeling frame will be a hindrance to others who prefer a solid grip and a balanced camera body--particularly if they're using a lens any heavier than the mediocre 18mm-to-55mm f/3.5-to-f/5.6 unit included in the kit.

Digital cameras must have at least a 4x ( VR ) zoom to be considered a candidate for the best camera. A powerful, clear, auto-focus zoom will help make your pictures look as if they were taken by a cameraman every time. Digital SLR cameras have a live meter reading that can be accessed by looking through the viewfinder at the meter bar on the bottom. Adjust the aperture and shutter speed until the meter bars are at "0.".

Canon is updating their line-up too fast, and this is bad for housing companies. Canon quality and reliability. Excellent value for money, particularly if you can still find a Rebel XT marked down to a close-out price, now that the XSi has come along to replace it. Canon lens 9475A002 can only be mounted on the Digital Rebel and EOS 20D with shorter back focus than ordinary EF lenses.
