I've found an assortment of developers to give brownish negs with several films, especially the slower finer-grained films. Sometimes the negs appear brown to the eye and sometimes not, but even if the brown tint isn't readily apparent a color densitometer will show it. Sometimes developing for contraction will show a stronger brown tint than N development.(posted 8489 days ago)Word from Kodak around the time Xtol appeared on the market was that a brown tone in negs frequently went along with fine grain. I don't know how valid that is, but I don't worry about it any more.
