Literally awe-inspiring!

A year and a half ago, I would have NEVER thought I'd get all cranked up about brownie and pinhole photography. Thanks to my fellow APUGers, I have lots of fun with my 'antique' cameras and am now chomping at the bit to make a few pinhole cameras.

Scootermm: how did you arrive at the pinhole size? Did you just make one that was convenient, or use one of the calculators on the net or what?
