If you're looking for pointers for taking better pictures or for an Online Photo community to exchange information, you may want to take a gander at Nikon's Digital Learning Center on Flickr. The Net destination launched today by the camera maker complements its interactive educational site at its U.S. Webstop. The Flickr site provides members of that photo community with tutorials, practical photography tips and live interaction with Nikon-sponsored pros, such as Rosanne Pennella, Cliff Mautner, and Nikon School instructors Reed Hoffman and Bill Durrence.
