Hello !
I have been lurking around the group for a couple of
months now and thought it was about time I introduce myself.
My name is John Douglas and I'm writing from the (COLD)
central Tennessee area.
I have about 8 years experience with LF cameras,
mostly my Speed Graphic
purchased a Kodak 5X7 as I wanted to
study the design of the back(s) prior to attempting to build
my own camera and I would really like to make a few contact
prints on Azo.

operation of a focal plane shutter? Are there single and double curtain

Think of it as a slit moving across the film plane. Although the entire
image isn't formed at the same exact instant, each part receives
distortion of parallel horizontal lines. Rise and fall produces an
effect similar to tilting the entire camera up or down, but doesn't cause
distortion of vertical parallel lines.
I suggest you check out The View Camera by Steve Simmons. Your local
library might have it.
