Bill, You'll love both DD76 and Diafine!!! Been using them for years myself. I do think that Diafine is a higher acutance developer but they both are EXCELLENT. As you probably have read, 2 bath developers will not block up your highlights. The first bath just soaks into the film and the acual development takes place in bath b. Bath b will only develop out till the bath a is exhausted. This is what is called "compensating developers". You really cannot go wrong.(posted 8707 days ago)
