Professional Camcorder That Are Priced Reasonably

By Chris Campbell

This Cannon GL2 is a professional camcorder that has so many features that it may be difficult for users to really get the hang of its whole gamut quickly. Cannon has always had its roots stuck deep in traditional photography and so it may not come as any great surprise that this professional camcorder has an excellent optical subsystem.

If a young man or woman with an artistic bent gets a hold of a mini DVD digital camcorder for the first time they will be in creative paradise, able to use the a mini DVD digital camcorder for so many great endeavors that you'll be the favorite gift giver of the season.

When a young artist has a mini DVD digital camcorder he immediately sets his mind to making movies like his favorite Hollywood directors, and the wonderful thing about a mini DVD digital camcorder is that he actually can do a very good job even on a much smaller budget than the famous Hollywood directors.

The modern equipment in the video world is of a higher quality than professional equipment was just a few short years ago. With a mini DVD digital camcorder a person then just needs a little writing talent and ideas for a script and they can make a film, or rather make a digital video that can be shown to friends, used in college classes and even entered into film festivals.

The signal of the PAL camcorder is interlaced much like the NTSC into two fields consisting of 312 lines each. In addition, the PAL camcorder has several distinguishing features that set it apart from others. Some of these features are providing a better overall picture than NTSC as well as more color consistency between television and stations.

This may pose a bit of a challenge when used in real world situations and this may be another negative, given that users may want to perform these functions under time constraints. They may work well when there is no dearth of time but because some buttons are not easily locatable this is a bit of a hindrance.

PAL camcorders do suffer from a major drawback; the picture tends to flicker, somewhat like that seen on a projected film because there are only 25 frames displayed per second. Countries that have PAL are U.K., Germany, Spain, Portugal, Italy, China, India, most of Africa, and the Middle East, to name but a few.

With a mini DVD digital camcorder a filmmaker has everything he or she needs to create a film, right there in the camera bag. The only things lacking are talent - which the filmmaker surely has in abundance, and imagination which he or she also has as well. Add those two things to the mini DVD camcorder, and the filmmaker is ready for action.

A Digital Camcorder Allows You Be Truly Creative

By Chris Campbell

You are in the market for a new camcorder and for whatever reason you have decided to purchase a new VHS camcorder. VHS is an acronym for video home system and has been available for consumers for many years.

Perhaps you have had great success with a previous VHS camcorder and have convinced yourself that straying from a good experience is not a wise move. Or, perhaps, the purchasing of new cutting-edge technology is something that you endeavor to shy away from. This may be because you are being cautious about the new technology. Or perhaps it's just a financial decision knowing that the newer variations of camcorders can be fairly expensive.

Additionally, captured video were eventually commercialized and became an integral part of a successful television show that featured hilarious antics captured on tape. All of these elements have added to the continual evolution of the video camcorder.

It was a fraction of the size of the very large Beta machines they were carrying, and produced a much higher quality image. The small but versatile professional digital camcorder this reporter carried quite frankly made him the news more than the speaker at the conference, at least among his fellow journalists and documentarians.

For example, if your purchase of a VHS camcorder is to be used in your professional line of work, then the model may require a greater variety of sophisticated accessories. These professional features, that will enhance your video presentation, may be the difference in making the sale or not.

The CCD, charged coupled device, is basically a sensor that measures the light received through the lens of the camera. This measuring of light results in the image being captured with more intense image reflecting a higher electrical charge and a subdued image reflected by a lower electric charge. This recorded image, captured through the variances in light, are then displayed as imagery on our computers, televisions, etc.

Depending upon your comfort and need for all of the "bells and whistles" of a VHS camcorder, there is a broad range of available accessories. Some of these accessories range from zooming capabilities, editing capabilities, the size of the viewing screen, picture stabilizer, remote-control and nighttime or dimly lit room recording.

The video camcorder generally is accessorized with many features. One such feature is a zoom function. The motor, built into the unit, powers the accessories.

The second major component to a video camcorder is the built-in VCR. This VCR is similar to the stand alone model with the only difference being the size.

And for those thinking of a career in broadcasting, learning how to use a professional digital camcorder at an early age is something that can be accomplished through an internship or classes in a university, community college or trade school. The sky is truly the limit with a professional digital camcorder.

The Advantages of a Hi8 Camcorder

By Chris Campbell

You have been videotaping on your Hi8 tapes and equipment for many years. Not only have you invested a large amount of time, but you have invested your hard-earned dollars into this extensive hobby that has now become a passion. However your eye has been turned towards the digital camcorder. You realize that with this new technology the video is very sharp and appealing.

Perhaps, a compromise between what you have and what you want can be realized. This compromise can blend together your huge investment of time and financial resources with your Hi8 equipment and your desire to move into the digital camcorder world.

There is also the option of the Sony CCD-TRV138, which allows you to enjoy the simplicity of Sony Worry-free recording with this camera which includes a 20x optical/990x digital zoom, a 2 1/2" color swivelscreen LCD and NightShot Plus infrared recording system, which allows you to shoot a video in total darkness.

The Hi8 digital camcorder allows for the video camera enthusiast to continue using their Hi8 tapes and equipment, but provides the digital optics experience. The Hi8 digital camcorder will not only record new video in the digital format, but will also allow that same digital experience to be realized when playing the previously recorded Hi8 tapes.

Again, the key thing here is to take a little bit of time and consideration in regards to considering all of your options, so that your end result decision will be the best one possible.

Because of the variety of possibilities, this further explains and proves why you should make your judgment on choice of tape stock so seriously.

There are many places available where you can find an HDV camcorder, as well as HDV camcorder cases and other accessories.

Because of the multitude of options, it is especially important in this case to take some time and consideration in your decision, in order to ensure that you will have made the best possible decision in the end.

RadioShack is easily one of the most well known and respected companies, at which you can find basically every type of camcorder and other electronic equipment that is available on the market today.

Other features of the Hi8 digital camcorder may include features that enhance the recording of the video. These features take into consideration the filming of sports events or video captured behind the backdrop of snow or sand.

In regards to the different topics involved here, these can be as obscure as the specifics of tweaking the settings on a GPS device or as broad as learning about other people's experiences with that of VoIP phone services, for instance.

Digital Camcorder Accessories Are Necessary

By Chris Campbell

A digital camcorder accessory bag is just part of the job, and is definitely needed by anyone who is seriously pursuing a career in videography.

In fact, most professionals, whether they work strictly in video or in photography as well, wouldn't dream of going out into the field to work without a digital camcorder accessory kit of some sort. This digital camcorder accessory kit should include a bag, preferably with a shoulder strap, that has been designed to carry video and camera equipment.

There are even websites that are specifically built to help you compare camcorders or other items, such as Bizrate, whose entire website is set up in order to help the customer select several items and choose between them.

Bizrate is a company which is operated by Shopzilla, which is a leading comparison shopping service that was founded in 1996. The company's mission is basically to enable shoppers to quickly and easily be able to find and compare and buy every possible item you could think of.

In fact, each month alone, Shopzilla connects over millions of customers with thousands of stores, and it should be known that Shopzilla also operates the Bizrate consumer feedback network that collects millions of consumer reviews of stores and products each year.

With the optical choice, the camcorder's lens mechanism moves to compensate for external movement, and with the electronic option, the image that is captured by the lens seems to float on the CCD, and the camcorder then uses that of internal circuitry to interpret the video after the image has been captured.

They also offer featured brands, in order to make it easier for you to narrow down your search, and their most popular listed brands include that of: Sony, JVC, Panasonic, Canon, Samsung, Hitachi, Toshiba, Aiptek, DXG, Gateway, Mustek, SVP, Sanyo, Sharp, and RCA.

Some camcorders offer zoom microphones that enhance the subject's voice, and then some also come with a socket for plugging in an external microphone.

Therefore, you will soon realize that it well worth the small amount of time and effort to put into comparing the items, then it will be in the end and you didn't and you end up having to pay for repairs or find that the item you purchased is otherwise not what you wanted.

Using A Camcorder For Home Pictures

By Chris Campbell

As with any other type of electronic device, finding a camcorder repair service is of the utmost importance, even before you actually have a problem and require a camcorder repair service, so that if any type of technical problem occurs, you will already know what to do beforehand.

It is really quite simple to do. Hook your VCR or your older, analog video tape camcorder up to your digital camcorder, connecting in the appropriate ports with the proper cables, and start the tape while your digital camcorder records tape to DVD.

However, as technology advanc7ed, miniaturization eventually enabled the construction of portable video cameras and portable video recorders, meaning that they were now basically available as home devices.

Their opinion is that if your camcorder has been submerged under water for any period of time, you will basically have to go out and buy a new one, no questions asked.

Throughout the 1990s, camcorder sales had the unintended side-effect of actually hurting the still camera photography market, and among the mass consumer market, camcorders gradually replaced still cameras for that of vacation and travel use.

If it does have a DVD burner, then the rest is quite simple. This is a good time to do any editing that you might require. Then simply transfer the data onto the DVD.

The imager section in particular is considered as being the eye of the camcorder, and the recorder is responsible for writing the video signal onto a recording medium so that it is stored and can be watched and edited later on.

All of their repairs are done on-site, in that they ship nothing out to other repair centers. They also offer a completely free estimate on all camcorder repairs, and they pride themselves on having no hidden charges. They also know the importance of time, and take this matter incredibly seriously.

By storing it digitally you will always have it available and be able to watch it again and again.

Key differences between CCD and CMOS imaging sensors

Digital cameras have become extremely common as the prices have come down. One of the drivers behind the falling prices has been the introduction of CMOS image sensors. CMOS sensors are much less expensive to manufacture than CCD sensors.

Both CCD (charge-coupled device) and CMOS (complimentary metal-oxide semiconductor) image sensors start at the same point -- they have to convert light into electrons. If you have read the article How Solar Cells Work, you understand one technology that is used to perform the conversion. One simplified way to think about the sensor used in a digital camera (or camcorder) is to think of it as having a 2-D array of thousands or millions of tiny solar cells, each of which transforms the light from one small portion of the image into electrons. Both CCD and CMOS devices perform this task using a variety of technologies.

The next step is to read the value (accumulated charge) of each cell in the image. In a CCD device, the charge is actually transported across the chip and read at one corner of the array. An analog-to-digital converter turns each pixel's value into a digital value. In most CMOS devices, there are several transistors at each pixel that amplify and move the charge using more traditional wires. The CMOS approach is more flexible because each pixel can be read individually.

CCDs use a special manufacturing process to create the ability to transport charge across the chip without distortion. This process leads to very high-quality sensors in terms of fidelity and light sensitivity. CMOS chips, on the other hand, use traditional manufacturing processes to create the chip -- the same processes used to make most microprocessors. Because of the manufacturing differences, there have been some noticeable differences between CCD and CMOS sensors.

  • CCD sensors, as mentioned above, create high-quality, low-noise images. CMOS sensors, traditionally, are more susceptible to noise.
  • Because each pixel on a CMOS sensor has several transistors located next to it, the light sensitivity of a CMOS chip tends to be lower. Many of the photons hitting the chip hit the transistors instead of the photodiode.
  • CMOS traditionally consumes little power. Implementing a sensor in CMOS yields a low-power sensor.
  • CCDs use a process that consumes lots of power. CCDs consume as much as 100 times more power than an equivalent CMOS sensor.
  • CMOS chips can be fabricated on just about any standard silicon production line, so they tend to be extremely inexpensive compared to CCD sensors.
  • CCD sensors have been mass produced for a longer period of time, so they are more mature. They tend to have higher quality and more pixels.
Based on these differences, you can see that CCDs tend to be used in cameras that focus on high-quality images with lots of pixels and excellent light sensitivity. CMOS sensors traditionally have lower quality, lower resolution and lower sensitivity. CMOS sensors are just now improving to the point where they reach near parity with CCD devices in some applications. CMOS cameras are usually less expensive and have great battery life.

3CCD Camera Intro

Three-CCD or 3CCD is a term used to describe an imaging system employed by some still cameras, video cameras, telecine and camcorders. Three-CCD cameras have three separate charge-coupled devices (CCDs), each one taking a separate measurement of red, green, and blue light. Light coming into the lens is split by a trichroic prism assembly, which directs the appropriate wavelength ranges of light to their respective CCDs. Three-CCD cameras are generally regarded to provide superior image quality to cameras with only one CCD. By taking a separate reading of red, green, and blue values for each pixel, three-CCD cameras achieve much better precision than single-CCD cameras. Almost all single-CCD cameras use a bayer filter, which allows them to detect only one-third of the color information for each pixel. The other two-thirds must be interpolated with a demosaicing algorithm to 'fill in the gaps'.

The combination of the three sensors can be done in the following ways:

  • Composite sampling, where the three sensors are perfectly aligned to avoid any color artifact when recombining the information from the three color planes
  • Pixel shifting, where the three sensors are shifted by a fraction of a pixel. After recombining the information from the three sensors, higher spatial resolution can be achieved.[citation needed] Pixel shifting can be horizontal only to provide higher horizontal resolution in standard resolution camera, or horizontal and vertical to provide high resolution image using standard resolution imager for example. The alignment of the three sensors can be achieved by micro mechanical movements of the sensors relative to each other.
  • Arbitrary alignment, where the random alignment errors due to the optics are comparable to or larger than the pixel size.

Three-CCD cameras are generally more expensive than single-CCD cameras because they require three times as many elements to form the image detector, and because they require a precision color-separation beam-splitter optical assembly.

The concept of cameras using three image pickups, one for each primary color, was first developed for color photography on three glass plates in the late nineteenth century, and in the 1960s through 1980s was the dominant method to record color images in television, as other possibilities to record more than one color on the video camera tube were difficult.

Three-CCD cameras are often referred to as "three-chip" cameras; this term is actually more descriptive and inclusive, since it includes cameras that use CMOS active pixel sensors instead of CCDs.
