Some of my favorite photographic links
www.tripodcamera.com - link to the Tripod Camera Club (Dayton, Ohio) website
www.dpreview.com - a great website that offers reviews of new digital cameras, forums and a lot more. Stop by here before you make that new camera purchase !
www.bhphotovideo.com - one of the best online photo and video stores based in New York...they might not be the cheapest place on the web, but they are reliable and they have an excellent website.
Exposure Cheat sheet - link to a quick reference showing the relationships between iso, aperture and shutter speed.
