For large format film I like Pan-X plus (I use an 80 E.I.), and for 120 I like Verichrome Pan (I believe this to be an old emulsion). Both very slow emulsions.(posted 8594 days ago)I have what I consider to be some stunning yellow/green negs that have beautiful tonal qualities - and then again I have some horrible negs as well :-). All of my later work is exclusively processed in PMK Pyro. see www/mcfarlands.net for gallery samples.
