Anyone fancy Tri-X at 51200 asa + prominent grain.
Well these two arrived yesterday so I guess I will have to start testing with the Kodak Double-X.
Michael Weyl at Spürsinn sent me some advice as I use an ATL-1500 auto-processor but guess it will also apply to all rotary style development:
“It’s possible to use HCD in rotary developing process – but only the part with HCD-2. Please don’t use HCD-S (start process) in rotation. You can start with HCD-S by hand and use in second process HCD-2 by rotation. Even the ultra-short-time-development (extreme pull development – example Ilford HP5 + @ ISO 25) can not developed with rotation.
By rotation you need 10% up to 15% less development time, as specified in data sheet. Please test it, because rotations speed is crucial. Orient them on the highlights.”
The instructions are comprehensive and cover most films. The developer can be used as a two bath or you can just use the second part. I have put the PDF on my server for those that might be interested.
