Hello,
As it is no longer possible to get Tri-X 8x10 film in Europe, I am looking for a new film to use. I have bought a box of ADOX CHS 100 / Efke 100 and would like to ask for help with developing ADOX CHS 100 8x10 sheet film using a Colenta rotary processor. I’ve read through lots of forums and sometimes people recommend Rodinal, but that isn’t available in Belgium either. I’ve always developed my Tri-X films in D76 1+1 and found that worked very well for developing ADOX films in a simple developer too.
I’ve found a development time of 10 minutes for D76 1+1... ?
Any help would be welcome
Many thanks
Marc

In the developer table in the FOTOIMPEX catalogue, the Efke/ADOX 100 is listed as requiring 8 minutes in ID11/D76. You’ll have to test for yourself to see how accurate this is for development with Colenta; otherwise, have another look here: http://www.digitaltruth.com/devchart.html

Hello Marc,
I have used the following times and developers with Efke R100/Adeox CHS100 so far. Although my film format is only 4 x 5 inches, the data should be the same for 8 x 10 as well. I always develop in a Jobo/Rotation unit at 24 degrees with a 2-minute pre-warm! This development process is tailored to a Jobo enlarger with a split-grade head, i.e. mixed light. The gamma value is approximately 0.65. So here are a few times:
Development in Calbe R09/Adolux APH09
1:40 equals 9.00 minutes – ISO sensitivity 80 ASA
1:100 equals 27.00 minutes – ISO sensitivity 80 ASA
1:60 equals 9.00 minutes – ISO sensitivity 64 ASA
Development in Promicrol
1:14 equals 6.30 minutes – ISO sensitivity 80 ASA
1:19 equals 8.50 minutes – ISO sensitivity 80 ASA
Development in CG51 / or Cube SX
1:4 equals 12.30 minutes – ISO sensitivity 50 ASA
1:4 equals 18.15 minutes – ISO sensitivity 100 ASA
The above figures should probably suffice as guidelines for your rotary development. However, you will certainly need to make some adjustments.
Best regards
Lothar
