Thanks for the info on paper negatives.

Next question. I recently bought a 8x10 Calumet Csomething (green). I've current ly have two tripods, a Bogen 3020 and a 3050. I have in the past used Bogen's 30 47 head, but it tends to creep when used with a mamiya twin lens. The 3050 tripo d looks stout enough to work with the Calumet. Any suggestions on tripod heads?

The basic use I have planed for the camera for shooting local scenics, buildings , etc. Maybe a couple family photos if i can get the kids to stay still.

Thanks!
