Taking projector photos rule of thumb:
1) Darkened room.
2) Set your ISO to the highest your camera can do (400 or higher is best) to let in more light.
3) Use tripod if you can get one as image tend to blur if your hands are shaky with higher ISO.
4) No flash as it'll just wash out your picture.
5) Pause image of DVD movie otherwise moving image will blur.
6) Use LCD view screen of camera as it's more accurate than the viewfinder (generally).
7) If your camera has delayed shutter release (timer--the kind that let you run from the tripod to get in the picture), use it if you're using a tripod to minimize shaking of camera.
8) List screen size/type/gain (96"X54", DIY blackout material, 1.1 gain), distance from screen that photo is taken from, light condition (darkened room, readable light, etc.), projector specs (XGA, LCD, 550 lumens), source (STB Toshiba interlaced or progressive DVD player, HTPC, DVDo, Quadscan, etc.), input type (via VGA, Svideo, component, composite), type and resolution of camera (2 megapixels, Nikon Coolpix 800, resolution set on standard, medium, or high quality, on tripod, ISO settings, etc.), and photo size (JPG at 20k) to warn downloader of time of download and compression artifacts.
9) Explanation of photos (your impressions) as picture is only a taste of what the true picture is like.
I think if you were to get into digital photography, don't waste your money on VGA as it's not adequate. You should get a least a 1 megapixel ($200) or higher. Good luck
