Two years ago when I had the desire to further my photography I searched the internet for a knowledgeable community. I found many sites with knowledge, but few had a sense of community that I wished to belong to. Then I came across The Digital Picture . For my use it was the perfect balance of gear reviews and interactive forum. I shoot with canon gear and although the site is more feature heavy on Canon reviews, I think everyone will find articles of interest.
