Curious, E-6 development temps ..

[peter k.]

Curious, ... all the E-6 3 bath kits that we have used, have developing temps of over 100*f, but in their instructions it also shows that you can develop at a lower temp, with more time.

Not considering the forever time that it would take, is there a positive aspect of decreasing the density shift that occurs with each development because of its activation during the heating process? Would this allow the chemicals to have a longer shelf life, if the normal steps where taken to keep oxygen out during its storage?

I buy the larger quantity Fujifilm chemistry from Unique Photo in New Jersey. I use liter batches of chemistry within a couple weeks then toss. In the past I've had excellent results with the Tetenal 3 bath kits, I don't recall any issue with thermal cycles. I got great results and the concentrates kept well.
