No, it still uses the same general mechanism as the chromogenic monopacks we all know and love. The only difference is solubility of the couplers

Iirc soviets did actually look into this type of film. Not much, because of WWII reparations, but I saw it in a book. I already intend to ask where the new types of dye couplers were researched for Svema, so I can ask him about more or less readily available water-soluble dye couplers, but the...

University course, Ukrainian. Though, original language is irrelevant these days, AI is pretty good at speech-to-speech translation. He teaches at Shostka Institute of Sumy state University, but not anything photography-related. I didn't ask what specifically tho. Aight, added. My 2 cents- E6...

+, though I don't think I've ever heard of C41 films designed for ferricyanide Heh It depends on film tho Oh, no need to be thanking me. All I want is to save whatever I can. Maybe for a kinda selfish reason- I always loved the Svema's "watercolor" palette, and my "idiot's dream" is to shoot...

Svema used a "cold" Agfacolor-derivative process in all color products except DS 100 until the last day. He did work in Svema's film duplication factory later on, so he's most likely familiar with all modern color processes, just not from the R&D point of view

Ok, sorry for adding you work Thanks for your question, added to the list.

Hi everyone. I have contacts of Kyrylov Anatoliy Dmytrovych- former chief technologist of Svema. He helped me a lot with my graduation project, and was kind enough to agree for an interview. Actually, he offered to read a course of lectures for me, but I'm too much of "not a chemist", sadly...

No. AFAIK, only Forte did Developing solution formulas do look close enough to Fototsvet papers http://istoriya-foto.ru/books/item/f00/s00/z0000004/st010.shtml

It does seem to work, yes. There's also the phone number of the guy +з8о95о754594 (replace the letters with numbers, I know he has a Telegram account, probably Viber too) Regarding the being more considerate part-well, there's always a chance that your lens will be destroyed by a russian...

I think yes. My friend got the frontal element of his Rolleiflex restored recently. It's kinda hard to see bc he didn't take an intentional "before" pic(photo 1), but it's kinda worn and scratched, and pic 2 is "after".

Just try shooting with Volna. You'll love it

This is also important to note: " Citrazinic acid is one of the key reagents of the E-6 process. The reason is that by the technology for the production of color reversal photographic films the purple dye component is introduced into the material in excess. This is explained by complex optical...

Yup. There's a really good book abt homemade e6, but I can't attach it here as a file. https://fex.net/s/c8k0tzm . It's in russian, but as always, Google translate does a really good job

By citrazinic acid, not by pH(or not only by pH). It competes with magenta couplers

Turns out, there's already an answer, back in 2022 I still don't understand why they went with monodisperse emulsions, perhaps it's "training" for 1/3 emulsions of the future Color Mission III, but then wouldn't it make more sense to still use the traditional layer order? Btw, this explanation...
