I was hoping to get my hands on some Diafine for its ease of development and fine grain. Turns out that it may be rather hard to come by in this part of the world, so I started looking around for similar products - and found Calbe A 03 listed as a fine-grain developer for all types of B&W films, with a single development time for all films. Does anyone have any experience with this developer? Does it work well with Ilford and Foma films? Thanks.
