That makes my mouth drool. Priceless. I would mount that on my wall in a minute. I am all ears. Luminous charcoal. New to me. What is it? how? How hard? can I do it? Please? Show me... I have 25 compostions lining up in my head that I neeeed to do that way.
a wonderful paper. i can't get enough of it. it's graded, so you'll have to deal with that w/developers.
printed through tissue paper.
developers: two step bath. a soft developer (selectol soft) at a 1:5 or 6 dilution for 2:15 stand development; no agitation. then immediately to a hard developer (edwal ultra black) at 1:2 for 15 seconds agitated.
i use a running water stop bath. figure 5 changes of water or 1 minute.
a non hardening fixer. i use tf-4. w/tf-4; 30 seconds.
allow excess fixer to drip off.
straight to selenium toner 1:12 at 70f. agitate until you get an increased density in zone 0/1.
wash for 5 minutes.
put into copper toner. agitate until desired tone.
immediately wash. 5 minutes.
don't over dry it as it will curl if you do. it is otherwise a non curling fiber paper.
you will need to print this down because the copper will reduce density. figure a stop over your normal exposure.
