I print on 9 1/2 by 12 paper for the simple reason that I like a smaller print, I tend to print full frame, so with, say 6x6 negatives, my normal size, the final print is smaller than the paper, The reason I like a smaller print is that I like the idea that a viewer has to come up close to look at the print, that somehow, with a small print, they get drawn into the photograph, I have printed larger, up to 12x16, but always come back to the smaller size, also, I think they look great mounted onto 20x16 mounts,
This could have been written by me! (although I really haven't mounted my prints yet).
My favorite thing is to go where I've never been. D. Arbus
