Hello, I am having a focus problem with my old graflex graphic view. What I did : no tilts, no swings Focussed on a certain point, take picture, check focus after removing film holder. Focus check was always ok after removing film holder. Problem : plane of sharp focus is about 7 meter before the plane I focussed on and this on every shot. I think the ground glass is positioned ok, since this is very simple on this camera. What could be he problem ? Very annoying. Thank you !
