Kodak has set up a brand new coating facility and in the process, it seems that on most of the films they are using a new base, which, if I understand it correctly, has an effect on exposure and development. There are some big Ansel fans out there who still stick religiously to HC110 and Tri-X. Kodaks recommended time for that has gone from 7 1/2 min to 3 3/4 minutes, which has cause some knickers to get twisted. I've got the PDF's open here side by side for new and old Trix 400 and 320 - there do seem to be differences in Kodaks recommendations for most developers - though most not as much as for HC110 D76 @20c in a small tank has gone from 8 to 6 3/4 minutes. (can't compare Xtol, 'cause the old PDF doesn't list it and I'd have to dig out the Xtol pdf). Ted, I'll email you the two pdf's - looks like you might need to run some tests. Some have suggested in most developers the percentage change isn't enough to make a big difference - I guess it depends what you're doing... tim BTW - Ted - there's a chance I might be in Qualicum Beach and or Victoria at the end of the month for a couple of days - are you on your travels then? > -----Original Message----- > From: owner-leica-users@mejac.palo-alto.ca.us > [mailto:owner-leica-users@mejac.palo-alto.ca.us]On Behalf Of Jeffery L. > Smith > Sent: Saturday, January 11, 2003 2:46 PM > To: leica-users@mejac.palo-alto.ca.us > Subject: Re: [Leica] OT: Xtol developer with Professional Tri-X 400TX > > > www.digitaltruth.com goes to the trouble of giving different development > times for the new stuff.
