In the realm of digital photography, it often seems that the most advanced and expensive gadgets are the first to include the most innovative and unique technologies. Surprisingly, in the last few years I've seen ease-of-use features usually found in lower-end point-and-shoot cameras popping up in higher-end models. This is particularly evident in Nikon's low-end Digital SLR (single-lens reflex) camera, the Nikon D40, which offers the power of a professional shooter with an assortment of consumer-friendly features.
