The book is a compilation of his photographs made over a period of, I think, 50 years. He photographs much in the same way as Robert Frank. He has traveled a lot, and is really, I think, a careful observer of life, of nature, of cities, and the countryside. The pictures have a kind of "sadness" about them... not exactly depressing, and he talks about the difference between depression and sadness in an interview at the back of the book.
The pictures also take on some dreamlike qualities, but are made in such a down to earth way... one camera, one lens. And the sequencing is interesting... you'll go from the middle east to middle America with the turn of a page... the pictures relate, but in the way images in a dream relate. Somehow... he has managed to give the world a very specific look... his own I guess, like you might in a dream.
I'll confess, it took me a long while to warm up to his photographs. When I was a student, and, frankly, had not seen very many of them... I didn't "get" them. Now... looking at a 50 year retrospective, they are quietly extraordinary to me.
I think Photo-Eye has a book tease... and you can probably request it at your library!!
