A bit of a different type of photography competition here, the Nikon Small World Photomicrography Competition. Open to all, this contest offers some good creative challenges with nine thousand dollars worth of Nikon equipment as prizes spread over the top twenty entries as well as a trip to NYC as Nikon's guest for the top prize winner. Use of Nikon equipment for the competition isn’t a prerequisite, which makes it more available to all. You can find out more information here.
