My favorite image from a recent trip perplexes me. (I wish I could post a shot but it was just sent in for scanning.) The background (at "infinity") is sharp. The foreground (from three to six feet) is sharp. But the midground (immobile rocks about ten to fifteen feet out) is less than sharp. The lens was a Fuji A 240mm at f22ish; the only movement was rear tilt and front rise (front and rear swing and shift were locked tight at the null settings); the rig is a 4X5; the film holder was a Fuji Quickload.
Film flatness comes to mind as the potential culprit, but I have found no other shots from this trip that show the same abnormality - in fact a few shots from the same trip that were taken after the image in question were very sharp in the midground/mid image.
Can you suggest any other "potential culprits"?
Do some Fuji Quickloads buckle upon loading in an otherwise functional holder?
