That's a swell idea when a 4-year-old girl gets put on gallery walls, sold as prints, put in photo books. It's kinda pointless for her to not want those pictures circulating when she becomes an adult, isn't it?
The "Tomoko in the Bath" photo by Gene Smith is not supposed to be able to be seen anywhere. The rights to the photo were gifted to Tomoko's family and all publication rights were suspended. But that doesn't rip the photo out of all the copies of the Minamata book. It doesn't remove all the prints in galleries and private collections.
It doesn't remove it from Google image search, either.
Reality trumps ideology, unfortunately.
I like that someone up above unabashedly said that Sally Mann's photos constituted child pornography. They clearly don't. But the vehemence with which it was stated is what counts. That's what anyone who wants to defend the photos is up against.
You can't fight dogma with dogma. Everyone who says, "It's art!" "The kids approved!" "It's nudity, not pornography!" is just as dogmatic as those who say "It's filth! Burn it!" Some people will never not see an equation between photos of nude children and child pornography.
How do you go about making someone not find these photos obscene?
I don't find them obscene - I have liked her photos since I first saw them. So I don't need convincing. But I can understand how some people would have a problem. That something is art doesn't mean it can't also be unacceptable to large groups of people. That something is beautiful doesn't prevent some people from finding it vile.
It's a pointless endeavour.
