If you look closely, I do think the person(s) have been claiming modified pictures as the before and the original picture as the after picture. Not all of their samples do this, but it's particularly apparent in the http://imancom.com/samples/color_change section. The people are fuzzy in the before, yet crystal clear in the after. Not even with Unsharp mask and sharpen, could I make them look that great afterwards. (I tried). Even the "background change" lower after picture looks a little suspect, when looking at the top picture that first loads on their homepage. I'm not trying to be mean or pick on anyone, this is just my opinion.
