It probably doesn't bother anyone else near as much, but something that i feel really detracts from a processed photo is fake DOF, or blurring sections of a photo to keep the eye away from it. I see wedding photographers do it all the time. It's fine (and can be great) if you are going to take the time to do it so that it looks real or natural, but just blurring a section of a photo for whatever reason really screws it up IMHO. Just makes it look completely unnatural.
Does anyone else notice this effect?
