I may have used the tray process back in the 1950's, but this is certainly the first time in the last five decades.

Ilford FP4+ in Diafine (4min+4min), water stop followed by Ilford Rapid Fixer, wash, Perma-Wash, wash, Photo-Flo.

I chose Diafine because of its wide time and temperature latitude, and it seems to have been a good choice.

I'm quite pleased with the results. The negatives look great; no scratches or other atrocities that I can identify.

Anybody else using this method/combination?

Thoughts and suggestions welcome.

TIA

I develop 8x10 in trays but I use D-76 or pyro rather than Diafine. Works very well.

For Leigh, with that developer, you can't screw it up, everything is to completion. If using other developers, some good techniques must be used, otherwise you get streaks.

For Mike, Please don't use bare hands for any pyro chemical, or diamine P, or catechol, the stuff is toxic as well as very staining. In the 1950's I just thought it was a problem for the stains to last 10 to 20 days, it turns out that liver disease can be the result. Therefore, don't get it on your hands, save your liver for some good scotch!

I won't stick my fingers into Pyro, trust me! but thanks for the concern. I can use gloves with 8x10 because I only process a sheet at a time in Pyro. I'm trying to learn to develop them by inspection.

I guess that you have already figured out Mike that developing by inspection is an art, especially with pan film, just when it looks perfect, it is 2 stops under developed. With Ortho and the bright red light it is a bit simpler.

Some folks are only happy if they see lions, tigers and bears hiding under the bed.

Others see only dust bunnies.

Yep. Figuring out what it's supposed to look like is a serious challenge. You just have to keep doing it until you figure it out. Kind of fun, actually... ;)
