The picture on the right shows the result. To check this, I made my own experiment and developed two pieces of the same film at the same time, using the same chemical and same 30вЊ temperature but one in the Jobo processor and the other one manually agitated with my usual agitation scheme of 15 sec twisting and 3 inversions every minutes. This is not so much of a problem when using lower temperatures and longer times. The thing is that when using 38вЊ the development is so quick that agitation needs to be perfect in order to get even negatives. The instructions are written mainly for using a rotary processor so it is easy to jump to the conclusion that you need a processor for C-41, however, this is not the case at all. Temperature: why use 30вЊ instead of 38вЊ ? Bellow are the reasons / explanations / discussions / experiments for the different choices.

I would use a different strategy if doing higher volume or professional work. I believe that it is a good process for me or any body developing low volume manually. вЂ‹So far, that is the process that I have come to and I get results which I am happy with. I have not decided what the best strategy is as far as some possible drying marks vs some possible scratches but that is not specific to color negative film :-) I do not use and squeegee but sometimes remove some of the liquid from the film by squeezing it between two fingers.

StabilizerВ at 30вЊ for 1'00' with slow continuousВ agitation (with twisting the stick).

Repeat the last if the wash water is not clear (with some film it is necessary). 20 inversions, let it sit one minute + dump. Tap the tank and put it back in the 30вЊ water bath after every agitation.

Blix at 30вЊ for 6'00'В with agitation the first 15s (with twisting the stick) and 10sВ (3 inversions)В every minute.

Stop bathВ at 30вЊ for 0'30' with continuousВ agitation (with twisting the stick).

I dispose of the chemistry after the 10th batch. To account for theВ DeveloperВ being re-used and slightlyВ diluted, after the 5th batchВ developedВ with the same 1L ofВ developer, I increase the time to 9'00' instead of 8'00'. C-41 Developer at 30вЊ for 8'00' with agitation the first 15s (with twisting the stick) and 10sВ (3 inversions)В every minute.Load the film in the developingВ tank and put the tank in the 30вЊ bath as well for about 5 minutes.Prepare a water bath at 30вЊ to bring all chemicals to temperature (Developer, Stop, Blix and Stabilizer).Here is the development process I currently use:вЂ‹
