I used a Pentax Spotmeter V, metered against the darkest shadows I wanted detail in then under exposed by a stop. So with the last aperture value on the meter being f/128, and the pinhole f/180 I was good :P
I've been everywhere ooooohhh yeaahhhh still I'm standing tall.
I first tried pinhole on a workshop in 1999 and I was hooked-it gets addictive for sure!
