Photoworks, an online photo community that allows users to create their own storefronts, has declared October Photographer Appreciation Month. To celebrate, they've teamed up with Nikon to give away ten Nikon D40s. The contest runs through October 31 and is divided into ten "Photo Community" categories, including European Travel, Cycling, Adventure Travel, Genealogy, Family Travel, Garden, Dogs, Weddings, College, and Cruises. One winning photo will be selected from each category. Enter your best shot and you might end up with a new camera in time for the holidays.
