I've wondered about this too, but from a slightly different point of view. If more photographers had the balls to do what Gilden does -- i.e., there was a larger body of work of the "flash in your face" variety -- would Gilden's work still be noteworthy? In other words, does Gilden's work stand on its shock value alone?
