Ilfosol-S is terrific for slow, fine grain film. It is *not* a speed developer.

Try Microphen for Delta 3200 at any EI up to 12,500. This has become my favorite speed developer during the past 18 months of use with many different films. It strikes a nice balance between a compensating effect and maintaining satisfactory "snap."

For convenience I like Diafine for Delta 3200 at EI 1600. Remember, Diafine is a fixed speed developer so "pulling" and "pushing" are not possible.
