extended c-41 developing w/Jobo CPP2

hi,
i am about to do my first processing with the jobo,8x10 film and i have some questions if anyone has done this before? i am using the tetenal c-41 kit and it allows for an extended processing at a lower temperature,86 degrees...which i thought might give me more even results. the film being processed is kodak 400nc....

also, the directions state to "pre-heat" the developer drum for 5 mins...i assume this means pre-wetting the film with water for 5 mins at the correct temperature...but want to check to be sure....any advice will be welcomed...thanks all

Robert,

Preheating means that you put the drum on the jobo and run it in the water bath for 5 min. This preheats the drum, do not pre-wet the film before you put in the developer as it will probably dilute the developer too much. I would recommend using the developer at the proper c-41 temp and go with the standard times. The temp is critical for the developer, but not so much for the rest of the process. I have used the tetanal chemistry before, but prefer fuji hunt chemicals now for c-41 and ra4. much more economical.

With the jobo you will be able to handle the shorter times because chemical handling is so much easier. I assume that you have the lift, if not get one. If you are using the expert drums it should be a snap.
Good Luck, and let us know how things develop :D

robert, thanks for the reply.....i had thought the film might also need a pre-wash as i had read about issues with "uneven" development...but for this first run i think i will follow your directions....though i may still use the extended time lower temp....configuration....thanks for your input....

ok did my first group of 8x10 negs using tetenal c-41 color-tec chemistry at the lower temperature extended time ....the negatives were terrific...no visible color cross-over, long contrast range and very even development....so now i have a way tom see my results sooner and cheaper......ciao
