I thought, 75mm lens, 4x5" camera, darkening in the top corners, very even across the bottom of the photograph, must have given it a bit of front rise.
Regardless, this one certainly stands out.
I agree with you about the fancy centre graduated filter, it has made the 65mm lens super easy to use, even with the lens coverage being around 10mm bigger than the film on the long corners, exposing without the centre filter is completely out of the question as far as I'm concerned.
For a couple of years I have been waiting for the 75mm version of the SWD f/5.6 65mm Fujinon to appear. Late last year I decided that having a 75mm with just reasonable movements, is essentially the same as having a 65mm with practically no movement; one just crops.
