I went to the "Eyewitness: Hungarian Photography in the 20th Century" exhibition at the Royal Academy in London yesterday, which I enjoyed much more than many recent exhibitions I have seen. There were a number of well-known photographs by Kertesz (amongst many by other photographers) and it was a thrill to see actual prints, but they were almost all ones that I had seen before in books. So I wonder, how does the curating process work when putting on an exhibition? Is the curator aware of the photographer's entire output and chooses freely from it, or are there certain defining photographs that "have to" appear? If so, how has it been decided over the course of time which these photographs are? How much of a photographer's output never sees the light of day, and why not? I'm not complaining - just curious as to how the curating process actually works.
