Digibase
Having recently acquired a Digibase C41 kit, I note that in the instructions they don't suggest increasing times as more films are processed in the same batch. Also, they don't mention any rinsing between baths.
I intend to make up 500ml. at a time (that's what my tank needs) which apparently will process up to ten films. Is it really so that I won't need to change the times for the last few films? Do I really not need to wash in between baths? I would be most grateful for the experience of others before I start using the kit. |

I don't know the kit, but manufacturers usually know the best way to use their products most of the time. Hopefully someone will have used the kit and enlighten you further.

I have used other C41 and E6 kits and always had to extend times as the chemicals were used. I assumed it would also apply to this kit; logic suggests that the chemicals take longer to do the job as they become progressively exhausted. Puzzling.

I follow the Kodak C-41 instructions and rinse between the bleach and fix and then wash after the fix.
I also add a 3 min pre wash in distilled water. There is a massive thread on APUG about it and it's amazing keeping properties and capacity, think all your questions and more will be answered here's all 26 pages http://www.apug.org/forums/forum40/7...se-c-41-a.html I usually use it a a 2 shot, mixing 250ml of solution and running 12 sheets of 5x4 through it in 2x6 sheet runs, both at standard dev time. Sure I could put more through put at the price it is, it's not worth wasting £20 of film to test. Nice thing is you can order individual chemicals in small quantities from AG. (I'm using a Jobo CPP2 with 3006 expert drum)

Looking at that thread, it seems that others agree with you about the 2 washes Ed. In the past, I have used a stop bath after the developer.
One contributor reckons he has had twice the recommended number of films (40 from 1 litre) from his kit. Maybe the great capacity is what accounts for the fact that no increase in times is mentioned. It seems, also, that the keeping properties of both the concentrates and working solutions are excellent. Over all, people seem favourably impressed with this chemistry. I think I'll include the washes and possibly the stop bath and see how it works using the same times for all 10 films. |

I made up another half litre last week, having accumulated films for a few months. The concentrates were fine and the working solutions developed as follows-
6 x Fuji 160 220 size 4 x Kodak 400 120 size 1 x XP2 120 size All with no adjustment to process times, except for one of the Kodaks which I uprated by one stop. Given that 220 films are about twice the length of 120 I reckon that's pretty good going. I have a few 35mm films that I was just messing about with so I might try them too in the same batch. Sounds penny pinching I know, but curiosity is getting the upper hand. |
