Or it didn't work out. It took an alternative tweak the T-Max developer RS? to be able to be replenished. Or done so effectively with it's proprietary developer.* But i still very clearly recall the film coming out way before it's proprietary developer and what a disaster that was and reading all about how the Kodak engineers or chemists what ever they are used D-76 to tweak the film until they had it right to release and THEN went to work on a developer which would make it even better. One thing at a time. But was worse. If they had a secret formula way ahead of time which they sent to Eric and Sexton then that's great but I'd think HP-110 would be close enough. It's just another liquid Phenidone developer. It was never explained what made the T-Max developer in whatever version significantly different or better than HC110 and I'm not sure it is. I'm afraid I think of it as HC110 with a T-Max label on it. Throw me a bone anyone old enought to have been there (dico ruled) because I'm sure i was not living in an alternative universe at the time. I remember this as if it were yesterday. Or this morning. But what was the middle part again?** :) Mark Rabiner Portland, Oregon USA http://www.rabinergroup.com *Xtol by the way is unusual because it is replenished with Xtol. Itself, straight up. No separate stuff to buy and store with a high alkali level to spice up your old sludge. I don't recall this in any other formula I'm aware of. An advantage of Xtol which apparently is a big deal to small labs where every square foot is a big deal. **Fish called Wanda - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
