Does it matter if the same stop or fixer batches are used in B&W, C-41 and/or ECN-2? I've read that fixer shouldn't be used for both film and paper, but an old-timer retired pro told me it's a load of crap, that he did it all the time.
Do whatever you want, man.Yup, re-using. I am thinking of all the intermixing - that's why I'm asking before I do it.
Rethinking it, he isn't that old, younger than me in fact. Not really retired either, but selling non-chemical light-gathering devices at a camera store. He made a decent living doing custom darkroom work for several pro photographers back in the day.
edit to add: The reason this comes up is because I see a bring-your-own-stop-and-fixer ECN-2 kit at Ultrafine.
Both stop and fix are cheap enough to use one shot at least for film. I generally use C41 fixer diluted something like 1+10 or 1+12, one shot. In a Jobo system, a single 135 roll thus only requires something like 15ml of fixer concentrate.Does it matter if the same stop or fixer batches are used in B&W, C-41 and/or ECN-2?
No, he didn't. He warned against citric acid stop baths. Acetic acid is perfectly fine, and PE explicitly recommended it. As I recall PE never managed to recall exactly why citric acid would have been problematic. I have used citric acid often for RA4 prints with no detrimental effects, but never on C41 film.PE warned against acetic acid based stop baths for C41 several times.
In B&W, I use fresh fixer for film but use the same fixer for paper later without any ill effects. I I wouldn't use the same processing bath for different processes though.Does it matter if the same stop or fixer batches are used in B&W, C-41 and/or ECN-2?

What losses will you incur if that idea is wrong?
+1I think the issue of mixing is you may get debris from the paper in the chemicals, which could harm the film.
when I suggested to PE that I was doing that he exclaimed "that is bad for your film!"
I continued to cross process my film all in the same developer over and over again. I figure I don't really need to save anything for eternity.*
*if it is for a job I use fresh chemistry!

hi pbromaghin: believe it or not I know exactly how it will come out. unless it is something like royale pan 1350 I have exposed and processed for the first time. pretty much ever roll or sheet I develop comes out the same, and has for IDK 12 years ... I have a "system" ...But John, You never know what it's going to come out like anyway, so how would you even know if it worked?*
*Except for a job...
not to mention the river of time doesn't back flush ...I am all for being thrifty, but after you have gone to all the time and expense of shooting a roll of film, is this really the best way to save a few cents?

I'm not trying to save money. I'm trying to save the bother of mixing and keeping track of so many bottles containing the same thing. My poor middle aged brain is easily confused.
Remind me not to visit your fish and chips restaurant@koraks you're right, I always confuse the two

that has been debated for years. The definite answer is probably!A plain-water rinse before using each should be sufficient to deal with any excessive chemical carry over, shouldn't it?

I think that even if it was a bad idea, there would be no painful losses.
- I always think of this logic,,,,,,, What is the size of the expected losses (if they really exist)?
And based on the size of the expected losses, I made my decision.
