Hi Scott, Thanks for your answer. I was talking about processing s8mm ou 16mm with reversal b&w, with reel and trough. Everyone takes care of the chemistry and marks each time everything is used. And it's generally clean.
Indeed, we get good results sometimes and at other times not, that's what I don't understand. And the white marks are as you describes, larges and elongated. esther. ________________________________ De : Frameworks <[email protected]> de la part de Scott Dorsey <[email protected]> Envoyé : lundi 6 septembre 2021 16:25 À : [email protected] <[email protected]> Objet : Re: [Frameworks] chemistry in artists-run labs C4? Do you mean C41? What are you processing and how? Reel and trough? Rewind tank? Is someone taking care of the chemistry and marking each time everything is used? Are people clean or is there carryover? You get good results sometimes, but at other times you do not? Photograph a step wedge for a couple frames before each roll and if something goes wrong in processing in the future you'll have something to check. Do the white marks look like air bells? Very small, very round, and totally white? Or are they larger and more elongated, like hypo getting splashed on film before development? --scott -- Frameworks mailing list [email protected] https://mail.film-gallery.org/mailman/listinfo/frameworks_film-gallery.org
