I've been studying Miroslav Tichy a bit, here's an interesting quote by him.
I actually like his work and his attitude.Photography is painting with light! The blurs, the spots, those are errors! But the errors are part of it, they give it poetry and turn it into painting. And for that you need as bad a camera as possible! If you want to be famous, you have to do whatever you're doing worse than anyone else in the whole world.
Here's a couple more links.
Another artist I just learned about this month is Deon Reynolds.
He uses old, reloaded, panoramic, disposable cameras.
