Carl, with my apologies, I want to throw in my 2 cents on Sturges to address Leon's question. Apparently the children are fine with Jock's work as they grow up because he has been photographing the same families for 25 or 30 years and is photographing the children of subjects he photographed when they were young. I know Jock well, although have lost contact since he moved to the northwest. I've met a couple of his models that most who are familiar with his work would recognize. When I met them they were 20-ish and were two of the most intelligent, articulate and self-assured young people I've known. They come from a culture where nudity is perfectly normal and a culture that thinks our conservative, prudish attitudes are plain silly.
As for Sally's family work, I think they are much more than snapshots because the images often tell a story, and sometimes that story may not be pleasant. And often they recall emotional moments from our own histories. It doesn't hurt that her kids are very photogenic and are able to communicate to the viewer through Sally's lens. I think Sally is a true and brilliant artist and her work will be remembered amongst the masters of our medium long after the plethora of square, moody landscapes that are so popular now blend into oblivion.
Interesting thread! Jock, Sally and Emmet Gowin are all near the top of my list of photographic heroes.
