Dear Stephen,
I shoot 4x5 quite often using lenses from 47mm -- 500mm. All are fitted with Copal shutters. I have never experienced this "shutter vignetting" behavior. However, there *IS* noticable light falloff at the edges with wide angle lenses, regardless of exposure settings or time. My 47mm Schneider exhibits this, my 75mm Rodenstock is barely noticable, and my 120mm Schneider not at all.

Subject: Leaf shutters
When shooting using a camera with a leaf shutter, do any of you have a way to counteract the leaf shutter effect? I mean, it's certainly not what I would call vignetting, but it is very apparent the center of the picture is the brightest point. And, I know it could be taken care of in the "printing" process by burning the center down a little bit. But, is there an "in-camera" method to counteract the effect?
