    Hi everyone,

    I picked up an old Yashica-Mat in Scotland last weekend and it had this roll of film in it. Does anyone know which process would be required?

    OK, i have just read up that it used the C-22 process. My question then is, can it be cross processed or what are the alternatives?

    It will have printed on the backing paper either the letters C41 or C22. The C41 is little problem. You will have to send it off to somewhere like Peak Imaging in Sheffield or do it yourself in normal C41 chemicals. The C22 process is long extinct in every day use, but I am sure that someone on the forum can suggest a place to send it to get it processed.

    If it is C22 it will be at least 30 years old and it may not be worthwhile getting it done. You could always try developing it as a B&W film.

    It is Kodacolor-X.
    This film was the last of the Kodacolor-series to be processed in C-22.

    What happens when you develop C22 as BW? I might just do that and see what happens.

    You will gain a b&w film whose densitometric characteristics might not be optimal, as the silver image was only intended as intermediate step.
    Furthermore there will be a heavy orange cast due to the masking-dyes.

    Off all the sites I would have looked at for answers on this, I wouldn't have expected e-how, but for some reason an informative answer ended up there. Thanks $DEITY for search engines ...

    What a nice bunch of people you are :smile:

    I'll process them as BW and see what emerges.

    Thank you all.

    hi ghostman

    on my profile page i have color film that was processed in b/w developer
    the mask is HEAVY and orange but with current modern technology you will be
    able to get an image out of it ... i can't say how but you can go to DPUG to get
    the essentials ( hint ! )
    i process all my color stock nowadays in a coffee based developer made of sumatran coffee beans.
    i add a smidgin of print developer to it, and have no problems. i am sure any b/w developer will give
    you acceptable results !

    There's a place in North Dakota that can still process C-22 color film, I think. They specialize in old film.

    I'm in a small alpine country in the middle of Europe :smile: If there was someone locally I might go for it, but given the age of the film (it's obviuoly been in the camera for at least 30 years) I won't. I'll process it as BW and see what comes out. I can then give it the old digital scan and treatment.

    I'll post results here (if there are any)

    Hello All,

    I just ran in the same problem (found an AgfaColor CNS film exposed in old camera), and maybe I am not the King of google searches, but I am just unable to found anywhere
    an usable answer about time/dev combinaison used when B&W processing C22 films ! When this thread coming up in APUG, I believe I got it, close, but no cigars ! :wink:

    Just to precise this :
    - No, I am not going to send it to ProcessC22 in UK
    - No, I am not going to gather all the chemicals to make my homemade real C22 process... :smile:

    So, for all the good fellows who (or who has heard of...) developping in B&W C22 colors films, what is your departing time, using, for example HC110 ?
    I just got a bottle of HC110 only for this kind of works...

    Many thanks in advance,

    Best regards,

    Raphael

    Just as a side note, to avoid mixing things up: the CNS was succeeded by the CNS 400. The latter was no longer designed according the Agfacolor- but the Ektachrome-principle and was processed according to C-41.

    Film is at least 30 years old and stored under dubious conditions, probably not worth the bother to develop it.

    I developed the film this evening, 10 minutes in DD-X 1+4. The film is badly damaged but a few frames have some detail on them. I can see the shots were of a sports team, most likely a football team (British), from Scotland. I look forward to scanning them and trying to salvage some details.

    It was fun anyway.

    Hopefully the analogue God(esses) won't strike me down, but when you do the $can, make sure to use the color setting to help with that mask.

    Hi Ghostman,

    Thanks you very much for posting the time/dev guideline and your results, they are great, even if the film base is damaged, the latent image seems to be correctly developped !

    I have to try with my film, now.

    Best regards,

    Raphael

    Films that used the C-22 process had oily couplers that required benzyl alcohol in the developer. Agfa held patents on those that didn't need this special solvent. After the patents expired everywhere, we got C-41.

    C-22 developer
    This is quoted in the reference as the official Kodak formula for C-22 developer.

    Water 800 ml
    Benzyl alcohol 5 ml
    Foamex 0.01ml (anti-foam agent)
    Calgon 2.5 g (sodium hexametaphosphate)
    Sodium sulfite 1.85g
    Sodium bromide 1.4 g
    Potassium iodide 0.5 mg (500 micrograms)
    Borax (decahydrate) 58.8 g
    Sodium hydroxide 12.5 g
    CD-3 5 g
    Water to make 1 l

    pH at 75F = 10.7
    Develop the old Kodacolor (C-22 process) about 13 minutes at 75F.

    There was no Agfa patent that blocked introduction of process C-41 by Kodak.

    To the contrary, it was Kodak that together with that new process even introduced new types of couplers.

    Hi all,
    Just to give a feedback :

    Taken the jump with my Agfa CNS roll ; I tried 9 min in HC110 dilution B.
    The film come out completely back, and was problably exposed to daylight before.
    It was a try and it's a miss !

    Thanks you to all,

    Best regards,

    Raphael

    For anyone else who has this problem...

    I would suggest stand development in either a more diluted D-76 variant or HC-110 at something like 1 part dev to 99 parts water. I have done older film before that I found in cameras and this is what worked the best. Does not work well with slide film, but seems to work well with most color films of questionable nature.

    Holy crap dude! I've been looking for this forever!!

    See...

    http://www.apug.org/forums/showthread.php?t=111431

    Also, have any formulas for CN-17 and ORWO color transparency developer? Need both, going I make some batches...

    Is there a book somewhere that has all the old formulas for home mixing? I have a lot of expired film (like 30-50 years old) and the B&W stuff I've just experimented and figured it out, but even if the colors are all messed up I want to develop it as color to see what I get.

    Any info appreciated :smile:

    Hi all,

    Just found another film in an older camera, a B&W one, this time !

    I will open another thread into this forum on the subject.
