All my pyrocat negs are a greenish brown - but decidedly more brown than green. My attempts at using rollo pyro yielded almost neon green negs on the same films. I wonder if there are small variations in local water supplies that influence the type and degree of staining. Unless you do your presoak, stop and wash in distilled water, you will probably get slightly different results than a person using a different water supply. In general, though, I have found that pyrocat has the least amount of non-image stain of all of them I have tried - in my local conditions.(posted 8059 days ago)Clay
