The first half of the 20th century belongs to Picasso, and the second half is about photography. They said digital would kill photography because everyone can do it, but they said that about the box brownie in 1885 when it came out. It makes photography interesting because everyone thinks they can take a picture.
It's not about composition. It's the way you feel about how your objects should relate to each other. I've got lots of African statues and things, and the cleaner arranges them like soldiers, which drives me mad. So I have to rearrange them, and I must drive her mad, because I'm doing anarchy and she's doing military manoeuvres.
