I don't know if it's the abundance of stock photos in the set or the training, but the 'hypertune' default look of AI photos drives me crazy. Things are super smooth, the colors pop wildly, the depth of field is really shallow, everything is overly posed, details far too sharp, etc. Vaguely reminds me of the weird skin-crawler filter levels used by people like mr beast.

I think it is the fine tuning, because you can find AI photos that look more like real ones. I guess people prefer obviously fake looking 'picturesque' photos to more realistic ones? Maybe it's just because the money is in selling to people generating marketing materials? NB is clearly the only model here which permits a half eaten burrito to actually appear to have been bitten.
