E6 oversaturated red

[Misko78]

OK, Fujihunt 5L kit is new and fresh. I developed 10 E6 yesterday and red is oversaturated.

Films were:
1x Fuji Provia 100 120 expired in 2010 - looks normal it is my film and was refrigerated forever
4x Fuji Velvia 100 120 - don't know was it fresh or not, somebody brought this film to me to process it, but it was underexposed (exposed for skies), skies look normal
2x Kodak Ektachrome EPN 100 135 - expired in 2009, my buddy says that it was kept properly, red is slightly oversaturated
1x Fuji Velvia 50 135 - fresh exp. date 2019. everything look normal to me, even reds?????
1x Kodak Elitechrome EBX 100 - expired in 2012, my film, refrigerated since forever, reds oversaturated badly,
1x Fuji Velvia 100 135 - expired in 2017, reds oversaturated.

As i develop in ATL1000 i need to add 10% to get 7:15 for first developer as this is recommended by Jobo (actually 7:30) but ATL1000 CD time is 5:00 by adding 10% more i get 5:30. Fujihunt CD time is 4:00 but they gave a remark to increase it to 6:00 if overall density is too low. Could this be a problem?

Check pH and follow instructions to your kit (adding NaOH, cause your pH should be too low).

Tetenal's Colortec E6 booklet comes with instructions (here, PDF page 6, booklet page 10) how to adjust color balance. While films from different makers appear to react differently, I would assume that E6 FD and CD from different makers would be sufficiently similar that Tetenal's instructions should also work for Fuji's kit.

From your description I get the impression that expired film is more affected by this than fresh film. If you plan on using expired film and still expect decent and predictable results, make sure you have many rolls from the same batch for tests&experimentation before you use it for important subject matter.

I use this Elitechrome for couple of years. I bought 30-40 rolls really cheap and had nice results. Also i bough 30 120 rolls of expired Velvia and Provio from Fuji representative and it is perfect. I've read Fuji E6 tech bulletin and it says that overconcentrated reversal produces red and magenta tint. I've checked my mixing notes and realized that instead of 21ml of concentrate i've used 22ml not much but as my ATL adds 10% to all step maybe 12 seconds more in conjunction with 1ml more produced this. I already reprogrammed ATL and will do a batch od 7 films today and i'll report the results, but all films i have for today are fresh.

First batch and reds are like they should be
