RE: focal plane shutter theory

Murray
The easiest way to do this is by checking out a speed graphic. It has a
focal plane shutter. I think I have one you could borrow for a week or 2.
Let me know off line..@ aschmitt@aandy.org

Subject: [pinhole-discussion] focal plane shutter theory

This may be off topic, but the breadth of knowledge within this group may
provide me an answer (off list , if necessary).

I would like to understand (actually, analyze) the operation of a focal
plane shutter, for the purpose of building one for sheet film. I want to get
a grasp on calculating exposure duration as a function of slit width and
linear speed, I guess (or direction to what I should be thinking about).

Thanks

Murray
