I have never used a powder developer before, and it's slightly confusing since it has a short blurb on the packaging rather than the extensive datasheets I'm used to. What should I do to be careful about my health, seeing as I live in the city and doing it outdoors would be difficult? Is it overkill to wear a gas mask and steam clean the sink immediately after mixing?
Didn't mean to post and run; it's been a busy week. Thank you for your replies, they really helped me think though and visualize what I am trying to accomplish.
A friend has just dropped off some Arista lith developer, the powder A/B type. ( http://www.freestylephoto.biz/50022-Arista-Powder-A-B-Lith-Developer-1-Gallon ). I am going to start with this since it is purpose built for the task, but if I can't get the results I want I will definitely try some of the developers you suggested. It really is essential for the visual style that I have as few midtones as possible in the lith negatives and normal contrast in the other negatives, so playing around with contrast at the print stage would be very tricky indeed. To deal with exposure unpredictability, I think I'll use a more modern camera like my F100 and just bracket like crazy. It was cheap bulk film; why not?
"Arista Powder A&B Lith Developer is a two part, non-corrosive, economical developer specifically designed for use with Arista Ortho 2.0, Arista II Ortho Litho, Arista APHS Halftone and Kodalith films. It is also specially formulated for use in the the Lith Printing process of standard B&W photographic papers."

I think I'm supposed to mix each packet with distilled water until I have a gallon of solution A and a gallon or solution B. Then for film I just mix both parts before use and use guesswork on the times? I don't think the powder developer is in the massive dev chart, and I have read it's a completely different formulation than Arista's liquid A/B lith developer. Interestingly, the MSDS refers to it as NaccoLith, so I guess that it's the same product. Maybe I should be bothering Freestyle about this
Also, sidebar: is there any way to figure out the shelf life of the unmixed A & B solutions? I have a lith printing project I'm not quite ready to begin and it would be cool if the developer lasted a while.
Thanks again for your input!
