Been shooting 8x10 Efke 25 and was wondering if anyone was processing in HC-110 using a Jobo Expert Drum. If you are, would you please share you working film speed and development, e.g., HC-110 dilution, processing time, temperature, and agitation setting. Examples and comments on the results are always welcome also!

I found the even though Jobo recommended reducing the development time by 15%, that I needed the full time to have the proper negative density for 4"x5" in the 3010 Expert Drum.

What steve said about the jobo times.
I don't use hc110 so I can't help there but you need to do some tests since you're output method (scanning, cold light, condenser, contact printing) will require different results depending on which you're using.

I rated the film at 25. I developed it for 4 minutes @ 68F in solution B for the testing I did for View Camera that was was published in March/April 2003. I would probably use a more dilute mix and go for 7 to ten minutes.

I have been using HC110 at 1 oz to 31 oz, temp 68, when I process in an old Beseler Drum and motor base for 5 minutes.
