Shot 32 says "brightness enhanced for screenshot purposes". I imagine this is a recipe for being withdrawn immediately? :)
Not if you can alter the brightness in-game as well, which is often provided through the options.
Throughout the image there's strong artifacts that look as caused by double JPEG poor compression so I would say there is the possibility it has been altered outside the game. Especially because the other WildKard's AVP 2 screenshots look better.
But that's just a long shot guess.
They all seem very bright to me, brightness has probably been increased for all of them. Anyway, the artifacts could also be from just one compression at a very low quality level, I think if there are no other shots and you can see what's on screen fairly well, MG approvers are not too picky about that.
Brightness definitely seems artificially increased. I'm about to run through this game again... are these screenshots up for replacement? If so I'll grab some while I play.
