I agree with BoneBlaster. The Nikkon Coolpix 995 is a great camera with 3.3 megapixels. I've used one, but don't own one (yet). It does a good job with x-rays and anything else you want to doccument, however, I've heard that some people have had difficulty while trying to interface with their computer. You won't go wrong with this camera, but there are newer cameras that are 5 megapixels. Choosing a camera is tough with the rate technology is advancing. Best of luck in your decision making.
