My photos don't always appear as sharp as I think they should be.
I had a suspicion that the focusing was not staying put.

The other day when I was out shooting I looked at the ground glass after the exposure had been taken
& saw clearly the image focus was off a tad.

Any suggestions on getting things more stable?

Thanks in advance!

FYI: not sure if this is pertinent, but the camera is an older 5x7 Deardorff
(dates from around the late 20's)
the back standard does move around a bit if nudged, but goes back to center I believe.
