The formula was never published, but I think it is still available, although in gargantual quantities only, from Best Photo Industries, 2318 Watterson Trail. Louisville, Ky, 40299. It was used by Henri Cartier-Bresson in all those wild places he went and had to develop his films locally under all conditions. I would sure like to try it, if you should find a source, or make up a small quantity. Regards, Mitch.(posted 8713 days ago)
