Digital BW, The Print

Ken:

I'm not getting newton rings. I would venture to guess because my film has been tempered 
and is taught and flat when I actually scan. The original 8x pass takes about 45min. I then 
quit the scan and check the preview (you can see the film moves) then I re-tape and go for 
the 1hr30min scan. It's worth it. Occasionally I'll get a blurred scan do to a software error. I 
simply do it again after checking for film flatness.
