I find that I'm steadily liking Delta 400 more the more I use it, especially when I push it a little, and that's after using HP5+ since it was known as HP4. Delta 400 has a bit of a shoulder, unlike straight-line films such as HP5+, which is what I believe you're seeing as more latitude.(posted 8222 days ago)I use D-76H 1:1 and 1:3, rotary processing in the Jobo, 11'30"/68F EI 400 and 13'/68F EI 800 fwiw. Note that the push time isn't a huge increase over the normal time. Packaged D-76 and ID-11 should be essentially the same.
