I have been using the ID-11 Ilford developer with the HP5 and have had very good results.I use Ilford Microphen when i push the film. Grain is not bad when pushed to 800, but gets decidedly worse when pushed to 1200. My daughter is using D-76 in her college photo classes with HP-5 and also having good results. I use 7.5 minutes when using it at 400 with the ID-11. Hope this might help some.(posted 8977 days ago)
