This is what I was talking about but for my personal observation of how the naked body perception has changed since the 1970's, which is confirmed by many sociology specialists. In a few words, nudity is now often assimiled to trash and shocking material, which RML's post confirmed, because he went to speak of trash nudy papers to say that photographers still can publish nude pictures. I was speaking of high-level nudes photographers : Bill Brandt, Art Kane, Jean-Loup Sieff, Helmut Newton, Wyn Bullock, etc - certainly not of the trash stolen paparazzi pictures of naked show-biz people he mentioned.
Had photo forums existed 30 years ago, Sanders would NOT have had to post a warning disclaimer about his wife's photograph, because nobody at that time could have got shocked by it ; anybody would have seen nothing but beauty and grace in this picture.
Want a proof of what I say, Raid ? Let's go. Famous humanist photographer Willy Ronis, now 97 years old, was recently sued in court by a stranger woman he had photographed in... 1947. She was pushed-up by lawyers just to make money.
Times have changed a lot and this has many consequences for photography - I mean, photography which intends to be a testimony of contemporary history (e.g., street photography) or vanishing beauty (such as beautiful young women nudity) and doesn't limit itself to testing gear to death just for the MTF fun.
I wish we could see many photographs of Sander's ones level here at RFF.
