Today I got a roll back from a pro lab. Here is there dev and scan of a testchart. Better then what I have achieved but the gray background is still not the same all over the frame. I took a shot from the same position with the same settings with a Nikon D800 and the background was perfectly gray all over. So, is it the film or is it the camera? Strange if it is the camera because then I have the same error on to cameras. The other pics looks good to me, it's just visible on the more controlled testshots on gray seamless that I did.
