Anybody know of a book that gives good coverage of contact printing from 8 X 10 negs (advantages of Azo versus other papers, different contact frame arrangement s, light sources, etc.)?

Thanks, Nathan

No books available, but see my article on Azo in View Camera Magazine or on our web site at WWW.michaelandpaula.com

Azo has a much better tonal scale than other b/w papers, you don't have to have a contact printing frame, you can use 3/16 or even 1/4 plate glass, no bubbles or scratches, and if you are going to use Azo, use Peckham Amidol and a 3" natural brush for constant agitation, I also use shorter exposure times and longer developement time (3-5) minutes. Beautiful prints. Pat

Forgot, for a light source, if you dont have an enlarger, you can so what Edward Weston did, use a 60 watt light bulb wrapped in toilet tissue at about 2-3 ft. above the neg. connected to a timer. I use a black light. I have one six tube box that I use for Palladium printing and then I use a 65 watt house plant light for contact printing on Azo, at 3 ft. above and in a 10 reflector. The Azo prints very fast with that combination. Pat

I used to use a NuArc contact printing lamp that was designed for paper speed lithographic materials. It had a high output halide bulb inside a housing that looked like a Kodak bullet safelite, and a transformer box with six taps and a built in timer. Just had an area marked on the counter top to show where to put my contact frame. The lamp also has a filter drawer that will accept 3" poly filters. I think it would dial down enough to use slower enlarging papers.
