IPhone Photography Awards

The hands are the giveaway :P

You can tell by looking at the fingers and more specifically the finger nails that the photo isn't real, and that's with my (relatively) untrained eye. There are other signs too (the light and shadows don't quite work, woman behind the front woman's head looks like it's clipping through the front woman). This is obviously more obvious given that it was called out as fake, and if a professional photographer had represented it as real, maybe a contest judge could be fooled, but professionals should find the image at least suspicious (I would think).

Something tells me this was some kind of stunt, with the contest/event participating along with the artist.

Not saying that AI images can't fool the naked eye of a photo contest judge, just that this whole situation strikes me as odd.
