Especially in fictional fandoms, like comic books and popular novels? (For those who don’t know, photomanipulation involves taking an existing photograph and using Photoshop or other tools to change stuff to your liking, so the resulting image is of the person in the photograph as, say, a superhero, or a furry-type figure.)
Personally, I hate it. I can never see what the manipulator (I’m entirely unsure if I can even use the word ‘artist’) wants me to see; only the original, especially if (as is usually the case) the photo used is one of a celebrity or model. And, as my parenthetical implies, I’m entirely uncertain if it’s really “art.”
On the other hand, I can fully see that this point of view is hypocritical compared to my opinion on fanfiction (though it does synch up remarkably in some factors). And if it’s this popular, there MUST be people who like them. But who? And why?
