Digital Cameras

it improves because it captures a moment that has just happend. this way you can show someone what happend when it happend.. haaa. you can record a moment with sound as well, its a memory holder :)

280mAh :-) , no really, basically it puts out more power. Some devices can handle the extra power, but others can burn up. You take a chance when you use a higher rated battery than what the device was made for.

One can find a cheap digital camera with printer from retails like Walmart, eBay, Amazon and Best Buy. These are the leading retails which also provide other stuff related and unrelated to cameras.

Depends what your using it for

The only gold you may find in a digital camera are small slivers of gold used to establish internal surface mount wire connections on the pc boards. Probably nothing worth taking it apart to salvage for. TVs are known for having gold in PLASMA tvs in some of their circuit boards as well.

Selling a camera on the web is easy with the right options. Among the largest sites to sell a camera are Amazon and eBay, while a site like Craigslist enables a seller to keep their merchandise local and avoid seller fees.

CCTV surveillance camera systems are very highly rated. They specialize in their field and have great knowledge of what they sell. Their systems are user friendly even for the lay person. Best of all, they are competitively priced.

When you click the camera the shutter behind the lens of the camera opens briefly and lets in the light on to the film. I am no specialist and this is what I learnt in school.

The first video cameras were produced in the 1920s in support of the early television systems. John Logie Baird built a camera as part of his television system demonstrated in 1925. Philo Farnsworth made a fully electronic camera that was demonstrated in 1929. The video camera, or television camera, is a fundamental part of television so cameras have been around for as long as television has existed.

Color cameras were developed and trialled in the 1950s and were used commercially in 1954 by RCA when they began successful broadcasting of color television in the US.

The next ambition among developers was to produce a portable, combined camera and recorder. The size of cameras and recorders in the 1950s made it impossible to call any device portable. It took the development of video cassettes to enable a truly portable "camcorder"

They were first developed for television production, especially for news telecasts of on-the-spot events; but they were soon marketed as a family resource-the record keeper of milestones such as weddings and graduations and a baby's first steps. Now video recording has come full circle as amateurs make spur-of-the-moment videos of events ranging from slices of life of their family and friends to major disasters or scandals.

Developments in camera and recording technologies has made the video camera and the camcorder more accessible over four decades. Both size and cost have reduced steadily to the point where they can be included in cell phones and deliver a quality that is similar or better than the first domestic camcorders of the 1970s and early1980s.

No reason why not. So long as the physical size of the battery matches, and the voltage it delivers is the same - you should be able to replace it with the higher mAh battery.

Your home security system should be easy to operate, easy to understand and easy to setup. You never want to be outsmarted by your security system. People generally get a system to feel safer, but if you don't know how to use it, you will not feel safe.

Pictures vary greatly in terms of size and quality, both determine how much storage space they need. However, 1 gigabyte can store around 2,900 average photos or roughly 200 high quality, high resolution images.

On a Windows Vista system, the size of one pixel is 631 bytes, however, the size on disk is 4 KB, or 4,096 bytes. Hope this helps.

Lighting is very important, especially in portrait photography. But anyways lighting can help with any picture you take, it can change a whole perspective, it can give you a shadow, it can make day into night! :P You wouldn't want a picture that's too dark that you can't see anything right? Well lighting can help give life to the darkness of your pictures, or for example your outside and you want your subject to have a shadow, lighting can make that possible! It can help or hurt how you want you picture to be. You want your picture to look its best and lighting can help that :) I hope this helps!

Is it three movies of two hours duration each.

Nikon specifically states that the D50 can only accommodate up to a 2GB SD card. However, some users find they can use the 4GB card with their D50s (see Resources). Although not guaranteed, use only SDSC and not SDHC (High-Capacity) cards.

camera 200w. how much pixels in there?

That would be a digital camera or a scanner. More specifically, there is a CCD or similar chip inside the camera or scanner, and that is what "perceives" the information and sends it to a circuit board, and in some cases a nonvolatile memory card. Then the circuit board sends the data to the computer in a format the computer can read.

If one wishes to purchase digital key chains they are widely available at stores or online shops. One can purchase a digital key chain at Bed, Bath and Beyond, Amazon, eBay and DHgate to name just a few.
