tripanfal Posted January 2, 2008 Share Posted January 2, 2008 Anyone have any times in black and white developer for this film?Any developer preference? Just looking to get an image from this old film (I know it's color) Thanks, Chris Link to comment Share on other sites More sharing options...

david_lyga Posted January 3, 2008 Share Posted January 3, 2008 Cut off a small, exposed portion. Develop it in print developer for about five minutes. Then, fix for about 15 minutes. Then inspect. Color film takes a long time to fix, especially if old. To get an even clearer image, after fixing you can do the following in full room light: after fixation, put a few grams of potassium ferricyanide in a pint of water and add an ounce of film fixer to it. Do this right before immersing the film as this solution will not keep for more than about an hour. Immerse film in this for about 15 minutes with agitation.

tripanfal Posted January 3, 2008 Author Share Posted January 3, 2008 Found some info using this strange function called "search". I even found a similar thread posted by someone with my exact name. Sometimes I think I'm brain dead...It was late last night... Link to comment Share on other sites More sharing options...
walter_degroot Posted January 3, 2008 Share Posted January 3, 2008 in the last day or so someone posted photos from c-22 film processed in c-41 solutions. or am I imagining it? he had to develop at a lower temp as the old film would be damaged by being in hot developer. I think itwas a forgotten roll of film a photo of a flower with a caterpiller crawling out of it. Link to comment Share on other sites More sharing options...
john_shriver Posted January 3, 2008 Share Posted January 3, 2008 C-22 and C-41 use different color developers, C-22 uses CD3 (along with benzyl alcohol), where C-41 uses CD4. Long discussion with expert input here: http://www.apug.org/forums/archive/index.php/t-20548.html I'd say HC-110, dilution B, 9 minutes. Fix a long time.

tripanfal Posted January 3, 2008 Author Share Posted January 3, 2008 Just souped it. D76 stock 10 minutes @ about 70 degrees. The frame numbers are clearly there, but no images. The leader was shredded. I think the shooter shredded the leader from a camera malfunction and thought he was taking pictures as the film counter advanced. The film is from the camera in this thread: http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=00NrdA Link to comment Share on other sites More sharing options...

JDMvW Posted January 5, 2008 Share Posted January 5, 2008 I've got a roll of Kodacolor-X sitting next to me as I type, so regardless of older threads, this one answered just what I needed to know.<div></div> Link to comment Share on other sites More sharing options...
john_brown9 Posted January 8, 2008 Share Posted January 8, 2008 You could try C-41 chemistry @ 70℉. The C-22 process was originally designed for 75℉, so 70℉ will work. Just be sure to give 4x the process times in all of the baths, except the stabilizer. That would be something like 13 minutes for the developer and washes, and 26 minutes for the bleach and fix. I used to do this 10+ years ago, when working in a pro lab, somebody would come in with a roll or three of old C-22 film. It worked, but the colours were not optimum. Considering that C-22 film has been gone for more than 30 years, anything you get will be better than nothing! 1 Link to comment Share on other sites More sharing options...

Alan Marcus Posted January 10, 2020 Share Posted January 10, 2020 This film can be developed in most any ordinary black & white developer. Because of its age, it will have an abnormally high background fog level. Best you develop in a black & white developer less 20% of your usual time in the developing solution. Otherwise, stop and fix just as you would if it were your favorite black & white. Don't get your hopes up too high, old films are likely damaged by time, heat, chemical fuming etc. Both the stop bath time and the fix time will be about the same as if it were a black & white. film. This color negative film and its replacement, C-41 sport an orange mask designed to correct the magenta and cyan dyes that must be used. When this film is developed as a black & white, the base color of the film will be ruddy. This makes printing of the negative difficult but not impossible. Again don't expect high quality results. Also, the C-22 color developer this film was designed for has long since been discontinued. Because of this, it is unlikely that this roll will yield good quality color images. Best if you develop this roll using standard black & white chemicals. Link to comment Share on other sites More sharing options...
glen_h Posted January 10, 2020 Share Posted January 10, 2020 I was editing some Wikipedia pages, mentioning the CD agent that they used. While some might be interested in reproducing C-22 chemistry, I only wanted to know it for historical reasons. As far as I know so far C-41 uses CD-4, and is the only one to use it. E6, RA-4, and ECN2 use CD-3. Since people do cross processing between those, and it seems to work, CD-3 and CD-4 must not be all that different. It might be interesting to know about E2 and E4, also, and for that matter, also K-12 and K-14. I am only asking to get the historical record right, and have no plans to actually mix anything. (For actual C-22 film developing, as far as I know C-41 chemistry at C-22 temperature works as well as anything else. Likely not well unless the film has been close to frozen for all those years. Times would take some trial and error.) -- glen Link to comment Share on other sites More sharing options...
rodeo_joe1 Posted January 11, 2020 Share Posted January 11, 2020 (edited) To get a rough time, do a clip test. Snip off a small piece of film from the end of the roll, in the dark of course. Then in room lighting; dunk the clip of film into a small quantity of whatever B&W developer you intend to use. The developer should obviously be at the correct temperature and dilution. Give the clip of film a modal 'average' time - based on published times for all films. You can watch how quickly the film starts to darken. How quickly or slowly will be a clue to the final developing time needed. At the end of the 'average' developer time, rinse and fix the film as normal. If the developer time was about right, you should have a blackened piece of film with a density no more than about 2.5. This is just too dark to read a newspaper through, but not so opaque that you can't easily see a bare lightbulb through it. The orange contrast mask will make judging the density by eye a bit more tricky, but the 'just unable to read newsprint' test is a good guide. Obviously the time should be cut or extended if the density is way off the above. Maybe even another clip-test might be needed. The contrast mask will make conventional enlarging of the final negs almost impossible, but scanning should be no problem.

JDMvW Posted January 11, 2020 Share Posted January 11, 2020 Would you consider sending it to Rocky Mountain instead? Has anyone ever got film back from them? I'm not being 'hard' on them but back in 2010 they were in trouble LINK I don't know what has happened since. Link to comment Share on other sites More sharing options...
JDMvW Posted January 11, 2020 Share Posted January 11, 2020 I had some old files from the internet for B&W processing of color film, but all the links seem to have gone dead. A Google™ shows many sites and videos. The original post here was from 2008, so it's possible some answer has be found in the meantime. :| Link to comment Share on other sites More sharing options...
rodeo_joe1 Posted January 12, 2020 Share Posted January 12, 2020 Does anyone have an actual reference that says that C-22 uses CD-3? The, usually authoritative, British Journal of Photography has CD-3 as the developing agent in the formulary of the 1963 annual. With minor variations, the same formula is repeated in C.I. Jacobson: 'Developing'; Focal Press 17th revised ed. The formula in both cases is credited to Ernest Gehret. The original post here was from 2008, Doh! I usually don't get caught by Zombie threads.

glen_h Posted January 12, 2020 Share Posted January 12, 2020 I wasn't intentionally trying to revive a zombie, but it came up in a Google search for C-22 and CD-3. Wikipedia likes to have a "reliable source" which probably includes the British Journal of Photography. I wonder where CD-1 and CD-2 were used? -- glen Link to comment Share on other sites More sharing options...
Tony Parsons Posted January 22, 2020 Share Posted January 22, 2020 <snip> Doh! I usually don't get caught by Zombie threads. I need a wingman watching my six these days! Just means the film is a mere twelve years older, that's all Link to comment Share on other sites More sharing options...
