Essentially, a photograph is a near perfect capture of an individual. A fresco is a stylized representation of an individual. I an not saying photography isn't art. But rather, culturally, people are more willing to accept an abstract representation of a nude child rather than a photograph of one. I assume, because, people don't see the fresco as 'real' as a photograph. I'm sure cultural relativism plays a part, too. If something looks like a renaissance painting people are primed to accept it as art.
