I like his work very much and I was lucky enough to see a few of his photographs at an History of Photography exhibit in Seoul. His book Essays was on sale for a good price but, alas, sold out by the time I got there.
The iceberg shot reminds me of photos of gothic cathedrals I have seen. Beautiful sky. The trains and the people moving between them look like worms to me. Mechanical worms and a mass-of-people worm. Great photograph.
Does anyone know what kind of camera he uses for his photographs? Large format? 35mm?
