As many people have discovered, Alec Soth now has a blog and is one of the many fine photographers now writing about their work (and a bunch of other stuff).
Alec hasn't just appeared in his own blog, of course. Here's a snip from the Walker Arts Center blog which I like a great deal:
This is totally corny, but the way I think about it is I really close my eyes and I try to imagine an exhibition of pictures and see what kind of pictures what is it I really want to look at? and then go try to make those pictures. You never make those pictures, because they just don't emerge that way, but it takes you on a path. Recently, I was in Georgia and it was the beginning of a commission. What did I want to photograph? Like, I'm interested in hermits. So I do a little Google search on 'hermits,' 'Georgia.' And I find this Greek orthodox monastery in rural Georgia, and I go there and have this amazing encounter with these people. Those pictures weren't in my head Greek Orthodox monks but something developed and it took me on this crazy path.
