The iPhone does a lot of stuff: - correcting for lens distortion - automatically setting white balance - optimizing color and contrast - blending multiple exposures when it's dark and has some advanced denoising tricks (which sometimes gives photo's a bit of an 'oil painting' look) - sharpening to get that 'crisp' look (even if your lens is not that sharp)
