Rodinal and Xtol works well. I have processed sheets of Tri-X and FomaPan 400 2/3 in Rodinal (nice sharp edges) and then finished in very dilute Xtol for a massive compensating effect. This is particularly good for working with N-2, 3 or even 4 developments.(posted 8587 days ago)FortePan 400 is another dual emulsion film, the lower emulsion is ISO 50 and the upper is around 320 in daylight, 400 in tungsten. it is based on a now discontinued Kodak emulsion.
