This Question is directed mostly to Sanking. I have signed up for your carbon workshop. Would I be able to make negs that would be able to print on Azo and carbon. I'm working up FP-4 at this time, and Keying the negs to Azo#3. Last neg I tried was ES about 1.56 blue channel, it was a little contrasty still. To get it to fit Azo#3 I think I'm going to have to go back to 1-1-100. I'm down to six minutes now and don't want to go under 5. Shooting at ISO 100. To fit on #3Azo the nege are starting to look visually more like a condenser enlarger neg. I'm used to going for#2 paper. I tried it on some old E2 Azo a friend just gave me and it printed a little flat, about what I expected from all the data I've red so far. I read on another post to key negs to Azo #3 for pn-pd. I was wondering if it would apply to carbon also. I have my fingers crossed that enough are signed up for it to be a go. Thanks, John
