Here's a test shot on Royal Pan 4x5" that expired in 1965:



and here's a detail to show the grain structure of this film:



This was rated at EI 400 in Acufine with 1 oz. Edwal Liquid Orthazite per quart of developer. Linhof Tech V with 135/3.5 Planar, probably close to wide open using rangefinder focus.

You can see from the relatively light film edges that the base fog is still pretty high if the scan is adjusted for relatively normal contrast in the image, but the film had a pretty good density range so there's still some room there. Midtones were nice, and I liked the grain structure, but I decided it was not really worth bothering with except as an experiment.
