Anyone got times for Tmax dev 1:9 for films like Acros, APX100 & FP4.

I normally use 1:4 but want to try a weaker dilution.

You really need to test the film for yourself as the times that others have will do you no good. There is a lot of factors that goes into getting dev times and personal E.I. down.

Do a zone test for zone 1 and 8 and you will nail your times down. There is really no shortcut around it if you want optimal negatives that will print properly.

Yes I know of this chart but just wanted to know if anyone had worked out different times. The digitaltruth chart does not have any times for Acros at 1:9 so if anybody can help there?

I wouldn't expect too much consistency across methods used in digitaltruth charts.

Kodak's tech pub for TMax films, F4016, has times at 75F for dilutions of 1:4, 1:7, and 1:9. The amount of adjustment varies by film and processing method (small tank roll film, rotary processing) with TMax developer, but going from 1:4 to 1:9 increases development times by a factor ranging between 2 and 2.5. So if you have a good 1:4 time for your films, something just over double the 1:4 time would be a reasonable place to start testing when diluting 1:9.
