New Kodak C41 Chemicals / Question

[mshchem]

I wish film manufacturers had reference patches similar to control strips on all their roll films, at the end of a roll. It would have simplified troubleshooting development issues, even without a densitometer.

Oh ,that would be great!

With Fuji RA-4 chemistry there was no way, horrible green/cyan cast.

There is a way - run a couple of square meters of paper through the developer to season it. At some point it stabilizes. It takes quite a bit of paper...
With film, the same thing would work. One would "only" have to sacrifice a couple of square meters of C41 film to get there...

Yes, forgot to mention that I was doing one-shot. But the point I was trying to make was that I observed significant differences between Kodak and Fuji dev. replenisher and starter.

Btw, I’d love to hear how seasoning 1L of developer with a few rolls of film and then staying close to spec with replenishment for the next 100 rolls and no control strips works out in practice.

Yeah, I agree. To replenish nicely with color processes you should have control strips and a color densitometer.

I recently went through a bunch of outdoor portraits I took, 20 years ago, a good friend owned Photo Pro in Cedar Rapids Iowa. Dave did everything by the book! The prints on Kodak Endura glossy paper were stunning.

They ran control tests every day, the lab manage Laurie was terrific too.

It would probably work OK as long as the negatives only need to be scanned and it's OK that everything drifts in all directions all the time. That's the only way is see it "work" in a small-scale/home setting. Mind you, that would likely be perfectly fine for most C41 shooters.

thanks everyone!
By the way I also got a reply from Kodak through Freestyle that you don’t need starter and that you just use the replenisher.
Man, the difference in information is wild.

But regardless, the proper way according to all documentation is to do the replenisher plus starter. So that I shall do!
I’ll run a test against pure replenisher and see how it goes for fun.

I made a nice spreadsheet to make 2L batches of developer out of the LORR kit and Starter. In case anyone wants to have the volumes readily available.

There are tabs for mixing and developing Kodak D76 and C41.
Also I wouldn’t mind a fact check on my volume calculations.

Cheers!

You are doing it right.

Kodak doesn't manufacture this product.

Okay well whomever the mfr is. Photosys, whichever. They responded to my query to Freestyle about needing the starter or not and they said no, not if using one shot. Freestyle wasn’t sure and they did it want to lie so they asked the mfr. and that’s what they came back with.

Anyway. Dead horse.
