VP127 from about 1967 in a Certa Dolly, a few years ago. Fortunately for the girls, it isn't quite clear enough to identify them. (It doesn't snow in Seattle all that often.)

Oh, ok. I didn't notice it was a link to a movie. But I do like to remind people about using the Google search, as I have used it to find where many others came from. It is sometimes surprisingly good, and at others kind of funny. Sometimes it finds the wrong feature, and so matches the wrong thing. And sometimes I forget where pictures I took are from.

color developing Blix question
glen_h replied to Donald Harpold's topic in The Wet Darkroom: Film, Paper & Chemistry
I am back to this again, as I am looking for a darkroom sink. I think I want plastic, but 316 or 304 seem to be fine. But the discussion of C41 and bleach reminds me of some Kodak book. They suggest that with color negative film, when one wants to be most sure of getting results, to first develop and fix as a black and white negative. Make prints from that. (Or scan, but it might have been too old.) Then you put it in bleach, and convert back to silver bromide. (Then rinse as appropriate.) Only the developed silver remains, so that is what will be converted. Now develop it in C41 developer, which will work just the way it would have in the first place! Two chances for good results instead of one. In any case, the bleach is used along with a bromide salt, for the conversion back to bromide to work. I am not sure what the FeEDTA does without the bromide ions around. Maybe hydroxide. -
