Recently I picked up a copy of the Nikon School DVD called Understanding Digital Photography, Release Your Digital SLR's Potential. While it is clearly intended for beginners and perhaps some intermediate photographers, I just wanted to see how they present the topics and $15 is not so expensive. Overall it covers a lot of useful topics including exposure, portraits, amateur sports, nature, and low-light photography. A lot of the beginner questions frequently asked in this forum are covered. All shooting is demonstrated using, of course, Nikon DSLRs and lenses. The DVD is hosted by Bob Krist, who shoots a lot of travel photography for magazines such as National Geographic Traveler. It runs 45 minutes and is in the 16:9 wide-screen format. P.S. There is a companion DVD more dedicated to the D40/D40x. Since I don't have a D40, I didn't get that one.
