zsas, that is a good point regarding the volume used. I basically had carried over the volume from what I did when working with the Fuji Hunt C-41 chemicals, and wanting to keep volumes to a minimum I think that number is partly derived from the minimum that Jobo state is needed to cover 120 film when loaded in the tank on 3 reels.
Thanks for posting the photo of Part C too! That really helps... I've been wanting to buy a full-on color calibration chart for a while now, and I think this is going to be the reason I use to get one. With an upcoming family vacation, I'm planning on shooting quite a bit of negative & positive film, and don't want a repeat of this last run (which did surprise me given how consistent things had been before I started using the Rollei chemicals).
Here is a sample image from the set. I also notice a rather strange vertical band along the right edge... I'm a bit puzzled as to what would have caused that, since in the rotary tank, the entire width & height of the film would have been immersed.

Looks like a light leak to me

When turning from yellow to red this particular developer part is no longer applicable.
These instructions are part of the product specification provided by MACO:
"The very high life period of the original concentrates is min. 3 years.
(Retention samples, produced 5 years ago, are still working well)
The only exception is color developer Part C.
The life period of color developer Part C is 2 - 3 years, depending on the storage temperatures.
The coloring of the Part C concentrate has to be yellow.
If the coloring changes into red, the concentrate does not work anymore.
In this case, you can buy single replacements for Part C:
#RDC05FC 100ml concentrate
#RDC01FC 1000ml concentrate."
With kind regards,
Thanks for confirmation of Part C. Do you have an American distributor of individual chemistry?
I have only seen the full Digibase kits available here in the US.
Hi Sebastian... first thanks for the info, that is really helpful!
I ordered two of the 1000ml kits from Freestyle in the U.S. back in April 2011. When I went to open the second kit, the Part C dev was already a deep dark purple (not really red, but most definitely not yellow). That would suggest to me that the bottle was not airtight and that the Part C should be replaced with fresh chemistry. Since it has only been 4 months since I received the kit, it seems like there might be a problem with the way the kits are assembled if the developer Part C is not lasting for the 2 - 3 years that Maco indicate it should.
This is really helpful. I have the 1L kit that I bought a few weeks ago. I've been unable to get the negatives to look right and I did notice that my Part C developer is purple. I called Freestyle just now and they said there was an issue with the 1L kits and specifically the Part C developer in the 1L kit. For anyone else who has seen this, what do your negatives look like? Mine seem generally more pink than brown and on the thin side.
I can tell just by looking at the negative side by side with a roll I developed in January this year (with the Fuji kit) that there is a lot of color missing from the recent Rollei developed rolls. I'll try calling Freestyle as well. It's a bit unfortunate actually, because I called them right after I got the kits in April because of leakage from another bottle (the bleach was overfilled), and they promptly sent a replacement.
My Dev Part C was dark purple upon opening. I got the 1L kit too from Freestyle. Any thoughts Sebastian re this?
Well, this is a bummer. I just got the Midi kit - is this the 1L package?
