First, thanks to those who have answered my previous questions. This is a very f riendly and helpful board.
I have had a (several?) recurring problem with my setup, a Calumet CC400 with a Schneider-Kreuznach Angulon 90mm. I don't seem to be able to use much if any cam era movements without losing focus. Last week I took a shot with full rise, and a little added rise via a base tilt-type maneuver. The upper corners were vignet ted, and a circular, arc-shaped band extending about an inch below that was very out of focus.
A friend told me that the vignetting was likely caused by the bellows, but I hav e the short bellows wide angle version of the camera. And that still doesn't exp lain why large portions of my shots go completely out of focus whenever I try to add tilt or swing (and I have attemtped to refocus, BTW, to no avail). Am I usi ng the movements incorrectly?
Any help is appreciated, and thanks in advance.
