I have a durst laborator 1200 that I use for MF and 4x5 that is now giving me newton rings on ALL of my medium format negatives. The negatives are between two glass inserts in the carrier, which has never given me any problems until now. I'm not sure if AN glass is available, but I'm sure I could get some cut. My concern is that I will see the pattern of the AN glass on the prints, does anyone have any advice on AN glass with this particular enlarger?
Cheers
