in that case, it is in the mind of the beholder, right?

i can show you a perfectly beautiful photograph of a nude woman and get different responses from different viewers. i've directed many nude workshops and have had to ask photographers to excuse themselves as their comments weren't appropriate. and it had NOTHING at all to do with how the material was created. Imogene Cunningham has images that could draw obscene comments and she certainly never intended for her work to be perceived as porn. just beauty.
