I've been shooting B&W 35mm & 6x6 for years & am happy with the results.When I took my first photo class back in the earily '90's a friend of mine gave me (either I took it or he was going to throw it away) an Omega DII set up for 4x5.Not having a large format camera at the time I accepted the gift & put it in storage (couldn't use it without getting different condensers/lens cones and I already had a Beseler 23cII).A few years later I was given a 4x5 mono rail Cambo but only used it with a polaroid back.Now that I have young kids of my own (and the room),I'd like to combine the two and actually use the camera with sheet film & the enlarger together preferably to make 16" X 20" fiber based,archival prints (11"X14" is the largest print I've ever made before).What are the biggest challenges in my way?I especially want to know about tray processing sheet film & agitation?
