They only tested 35 mm (and not Tri-X 320), But found that: there was almost no difference in dev times in the emulsions they compared - old and new Curve characteristics old and new were almost identical. Biggest difference was grain - most emulsions were improved grain wise. Especially Tri-X. The Exception was T-Max400, which was now MORE grainy. In fact Tri-X had improved so much, it was now less grainy than T-Max400.. Testing was done by the ex-kodak product developers who developed Xtol and other things. Be interesting to see if this holds true for sheet film BTW - they couldn't figure out where Kodak got there new, and sometimes wildly different development times from. Their advice was to stick with what you've always done for a said film, and then see if there are any big differences. - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
