The New York Times has a new article on Robert Frank entitled "Snapshot from the American Road". Here's the link.
It's an article about the most famous photo book ever made, The Americans. Did you know that Mr. Frank shot 767 rolls of film while on the road? Man, that's a lot of film.
Yes, it is a lot film indeed, I have two books by Mr.Frank, The Americans and Story Lines.
What I've seen from those contact prints pictured, the man could use a full film at a spot, he shot many frames of the same scene, only with slight variations in composition from frame to frame.
