Thanks guys. This is my first time with PL100 in 8x10 but I have used it with Pyrocat at about ASA 80. No problem there. My belief is that it is the real speed issue here. Xtol is the one developer that can always carry off box speed but I'm
suspicious now. All the other factors such as settings; shutter and aperture are fine. The shutter is a brand new copal 1 in a 240 Germinar. I always recheck my meter. The Xtol was just out of the package. It's got to be the ASA setting. Going out to test this out right now!!
Thanks, Peter
