I'm a little torn: I switched from the iPhone 4 (not 4s) and have so far found that the s3's 8 megapixel can't shine a light to the iPhone 4's 4 mp camera. I feel like there has to be an app out there that will improve the quality, or at least work on the s3's autofocus and white balancing. I shoot with a Canon most of the time, but found that my iPhone had the capability to shoot stellar photographs as well. This *upgrade* to the s3 is a bit of a disappointment. HOWEVER, in EVERY aspect besides the camera, the s3 outshines the iPhone.
