I think that absolutely the best iPhone camera application is Hipstamatic. With the wide arrangements of lenses films and effects, it gives the user a great outlet for creativity. I hardly ever use the normal camera application in the iPhone. Hipstamatic is permanent fixture of the front page applications, for easy and quick access. Yes it only simulates certain old school film types and lenses, but it does it quite brilliantly. Here are some shots I took with it while driving around, one day during a lovely foggy, sad day. Enjoy.
