> I need the extra speed(posted 8898 days ago)OK, if you really need EI 800 you'll have to accept the increased contrast you get with HP5 in Xtol.
I suggest a developer that gives a little more speed with normal contrast. The "real" speed in the following developers is EI 640 when the film is developed to "normal" contrast.
HP5+ in Microphen 1:1
7'/75F EI 640 8'15"/75F EI 1000
HP5+ in DD-X 1:9
7'/75F EI 640
HP5+ in DD-X 1:4
9'/75F EI 1600
If you can stand the increased graininess:
Delta 3200 in Microphen (straight) 7'/75F EI 2000.
