Whew!

I've tried it now - with projection printing...

Using my Durst 138S, condensor head, 300W opal bulb, Rodagon 180mm, a 5x7" negative on 8x10" paper worked well at exposures in excess of 2 minutes at f:5.6.

Developer was Gevaert G262 at 1:8, it took 4 minutes for anything to show up on the print. It was still developin when I pulled it out after 10 minutes. With this combination the contrast can be controlled in a "lith-like" way, a second print at 5 minuts exposure, yanked after 6 minutes in the soup, was of considerably less contrast. I would say the contrast on the first one was about what I'd expect from a grade 4 paper, the second one about 2.

Image tone is very cold, but warms up a lot in Selenium toner. For comparison I did a print on Kentmere Art Classic, at "normal" exposure. The print was the brownest I've yet seen without toning - but cools off to a nice tone in selenium...
