g'day Kurt, the best way to increase shadow detail, and lower overall contrast is to overexpose and under develop
I have recently been using this technique with Agfa APX 400 and obtaining beautifully detailed negs
I rate the film at 200 ISO, and reduce development time by 20%
as a starting point this technique works with any film/developer combination, you may need to tweak it for your own requirements, basic formula is halve ISO and reduce time by 20%

Ray has given you some good suggestion. We use HP5+ all the time . Most of the students rate the film at 200, a few at 160 (but they have done film test to determine the specific EI.)
We are also using HC110 solution B , using the recommend times . Lots of detail, etc.

Thanks.. I shot a couple rolls of Ilford Pan F ISO 50 at ISO 25. I'll see how it develops and scans in tomorrow.

Personally I use Diafine; it allows great shadow detail and holds the highlights well. I played around for years using D-76, Id-11 and such but now all I use is Diafine. Nothing can be easier either, 3 minutes in each bath, 30 sec stop bath (tap water) and fix and that?s it. It is not temperature sensitive, as long as the chems are between 68 and 85 it works. When I shoot HP5+ I rate it at 800, expose for the shadows and let the developer work. I have yet to have blown out highlights. Now Diafine is not perfect, some films just don?t play well with it like T-max and Delta (they work but some don?t like the grain produced) but older emulations (Tri-X, FP4, HP5...etc) work wonders in the stuff.

From what I read about Diafine, it sounds like an interesting developer. The snag is that it may be hard for me to get it considering I'm in Kansas. B&H claims that it can not be shipped due to regulations. I assume that you pick up your Diafine locally?

Hmm.. I was groggy this morning at 6am and did not do enough searching around. B&H won't ship Diafine, but Freestyle and Adorama will.
I do have a question about storing it. I have been using the university's dark room, so I'll need to have my own storage container. It says that it makes up one gallon, but it is a two bath developer. Does this mean that each part is one gallon? Or that each is 1/2 gallon? I'll need to order a couple plastic dark room jugs, but I need to know which size. Thanks!

Okay, I need to just be more patient and google more throughly. From a larger picture of the box. It says that it makes 1 gallon EACH. :)

Thanks for the reply. Out of curiosity, how many rolls of 120 can you process from the one gallon of Diafine?

I mixed my current batch of it over a year ago. It's still going strong and I have probably done 150 to 200 rolls of 120 and a bunch of 35mm. This stuff last forever.
