Michael R 1974 -

I must say, Barnbaum's book has been the biggest photographic inspiration for me yet (as well as Michael Kenna and Vivian Maier prints). Barnbaum has a couple PhD's and spent at least a part of his career in Mathematics, so it is line with his ideology that he seeks to explain part of photography systematically or mathematically - which is partially what the ZS is, if i understand it correctly.
