PE recently posted Kodak's compensation times for C-41 developer reuse. Those of who wet print like consistency and repeatability, and you lose that when you start reusing developer and adjusting development time. Of course if you get results you're happy with, there's no right or wrong answer.Even with separate chemicals, one liter of developer is enough to develop up to twelve to sixteen rolls either all at once or one at a time. Why use it as one shot? Either replenish or throw out after to limit is reached.
Forgive me for reviving an old thread. Someone else mentioned this info/chart in another thread. I have searched and searched and searched for PE's post using all combinations of terms I can imagine. This is exactly what I am looking for, yet I cannot find it anywhere.PE recently posted Kodak's compensation times for C-41 developer reuse.
Thanks @Donald Qualls! That's a good start. I realize it will require testing and does not yield official or accurate results across all films/developers/etc. However, PE's compensation times/chart has been mentioned a few times and I want to find that. I've found one for Fuji Hunt and one for Cinestill, both on other sites, but cannot find the one mentioned here for the life of me.Seems to me I recall Kodak recommended an extra 0:15 per roll past the 8 rolls they recommended for a liter, but I could have recalled that incorrectly.
If anyone can locate this--or teach me how to locate it, I would be much obliged!!PE recently posted Kodak's compensation times for C-41 developer reuse.
Thanks for following up. I was afraid of something like that. Still, the post or thread should've contained at least some searchable text, right? Is it possible to search for posts and replies "by user & with attachments"?IIRC, PE's post was of a scan of a page of a printed instruction sheet.
The search function doesn't work on images I'm afraid.
If you can point me to that publication, I would be much appreciative. I've searched well into the night the past 2 days, and can't seem to get it.I'm pretty sure I found the 0:15 per extra film recommendation in one of Kodak's publications that was referenced in another thread here within the last 3-4 weeks.
This made me giggle. I'm still so sad he's no longer with us.One of the fascinating things about many of PE's posts is that they are difficult to search for if you don't know the particular terms he was using.
Good detective work.
Hey--that's awesome! Also, very helpful!!! I think I was taking photos on a Kodak Discman back then.The reference in that scan to one pint, along with Kodacolour II, may give you some sense how old that document is.
It was good that you found it, because it made me think - check my 1982 Kodak Colour Darkroom Dataguide.
I have no idea - I've never done this myself.I see on p13 of your dataguide that the two film types listed back then have a different max capacity. Where would you put modern films? Using 135-36 as an example (per pint in the chart), the max is 10, and 8. Would modern films be able to exceed that by, say, one "process" to 12? I'm speaking theoretically as a starting point for tests, not definitively.
Cheers--thanks @MattKing!! Ultimately I'm looking for a starting point for time-increase and exhaustion rates when processing modern films in C-41. I realize I'll need to test my workflow once I get the starting point. I'll check the other thread. Thanks again!I think I would ask people who are currently processing old film whether they notice their chemicals exhausting more (or less) when used with old film than with current film.
I saw that. It's within the margin of error with a hand tank, so 15(ish). Ha. The Cinestill kit dictates 2% more time per roll up to 24 rolls (with 1 L of mix), which, I believe, compounds with each successive roll. Cinestill pointed me here for a time chart (I hope this dude got a few rolls of free film and a free kit for his effort). I'll likely experiment with their extension method with hommeade mixes at some point and report back. But that's down the line.the Data Guide confirms 8 rolls of 135-36, with time compensation actually less than 15 seconds per roll (thinking about it, that may have been the Cinestill kit that had that figure).
