You don't mention time or temperature of development. Also, can I assume that you are developing your negatives for an alternative process that would require a negative with a fairly high CI (high contrast)? I ask the question because I only recommend the 2:2:100 dilution of Pyrocat-HD for alternative processes. If you use this dilution with negatives destined for silver printing (except AZO) it will give to much contrast in most lighting conditions.
