I use 5 liter kits that I store in 1 liter bottles. I use Xtol 1:1 and use 1 liter to develop 8 films. If I use less I just discard the remaining Xtol. I'll find some glass bottles to store the stuff, besides, I alway wanted to try the stuff at 1:3, so I guess the small bottles will come in handy. > > I assume you are using it one shot and tossing out the spent > developer.

I thought that too, but last time I had a similar problem with 4 rolls of TMX, shot in the studio with a R8, same lighting conditions, same exposure and 1 film (same development tank) came out "under exposed" or "underdeveloped" - I just can't figure this one out. I couldn't check the film batch number, because I had discarded the boxes a long time ago. That's why I was wondering about the "aging behaviour" of TMX... > > Regards, > > Robert Merci, Tarek - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
