I have a choice of using Rodinal or Ilfosol S on a roll of Kodak's HIE Infrared film. After checking The Massive Dev Chart, I found I could not find times for Ilford's developer. I am a little worried about using the Rodinal as the HIE already tends to be rather grainy and for this school project I need to minimize grain as much as possible. Has anyone here ever used Ilfosol S on HIE? Anyone have development time suggestions? Or should I just go out and get another developer?
