I've been using diafine with tech pan with great results. The key is

to develop in the "b" solution for exactly 1 1/2 minute to keep the

contrast normal. Diafine is a two solution developer that is

insensitive to temperature (between 70 and 85 F), to inconsistent

agitiation, and to developing times, except in the case of tech pan in

the "B" solution. Cost is also low, a factor to those of you who use

technidol.

Use the Ilford archival processing system to reduce water useage. The

total recommended wash time for FB prints is just 10 minutes, 5

minutes before the wash aid and 5 minutes after. I didn't believe this

at first, but I read the technical paper published in a peer reviewed

journal, and from the view point of a practicing chemical engineer for

36 years, I have made the switch. If you would like a copy of the

paper, let me know or you can request it from Ilford by e-mail.

The whole sequence is takes just 22 minutes, this approaches the

porcessin and wash times for RC papers.

Use the recommended exposure of 1/60 at f5.6 with a 25 filter as a

starting point. Use the development time for plus-x 120 film as a

starting point. If your film is like the batch I got, there is no

information in the box. I contacted Konica and they sent me the

technical sheet for 750 and I can fax it to you if you would like.
