I got these off of
this guy's blog. He wrote that Evans only got the 'roid in his last few years of life. He hadn't done anything in years, but was newly inspired once he got his hands on the newfangled SX-70.
"I bought that thing as a toy, and I took it as a kind of challenge," Evans explained. "It was this gadget and I decided that I might be able to do something serious with it. So I got to work to try to prove that. I think I've done something with it. After all, I am getting older, and I feel that nobody should touch a Polaroid until he's over sixty. You should first do all that work. It makes things awfully easy to have that thing pop out. It reduces everything to your brains and taste. It interests me very much, too, because I feel that if you have these things in your head, this is the instrument that will really test it. The damn thing will do anything you point it at. You have to really know something before you dare point it anywhere."
Not totally sure how he took this one. 
This is the guy who was taking all these pictures.
