Try a known film recently exposed in a normal Xtol process for you. If thin then it is the Xtol. If normal then that variable is eliminated. 2)Acquire some fresh Neopan, expose and process in the now vindicated Xtol. I personally would do a bracketed exposure from 5 stops under to 5 stops over. If it comes out OK implying that the film in question is indeed damaged by time then by comparing densities you have some direct way of plotting how many stops to push the old film to come to some kind of normal negative. So: Known film exposed properly developed in suspect Xtol: Normal density then Negatives thin Discard Xtol and mix new batch Expose fresh film in bracketed series Start with new film exposed at and develop with original time. Compare your normal EI for Neopan densities with original thin negs and approximate new time for pushing the old film. Why ask for anecdotal evidence when finding the truth for your situation is so easy? Don dorysrus@mindspirng.com - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
