Julius Shulman, Case Study House #22, Los Angeles, CA (Pierre Koenig), 1960
This is exactly as described: a wonderful ambiguity. In cityscapes with oblique lighting and long shadows, almost lit like a film noire set, strangers are caught going about their business but in such a mysterious way that the pictures throw up curious narratives. They are nearly all black and white, and some are by the masters of reportage. But there are also many great photographs by people you would never have heard of.
