Pushing Vision3 500T

Cerebum · 2025-11-29T17:45:44-0500

I am shooting a showcase at a community centre tomorrow. I have 500T and was wondering how successful pushing it to 2000 would be. Also, I home develop in C41. I found a suggestion that 1.5x is right for a two stop push. Question is, even though technically 2000iso is two stops, do I need to make allowances for cross processing? Any advice is gratefully received

No clue about the cross processing aspect, but I've successfully pushed 500t to 2000 in ECN2 by following https://www.kodak.com/en/motion/page/push-pull-processing/ and developing for 4:40

That's encouraging like I said, the one suggestion I found was to apply a multiplier of 1.5, but that was probably referring to ECN2. What is the rule of thumb when pushing standard colour film?

https://business.kodakmoments.com/sites/default/files/wysiwyg/pro/chemistry/z131.pdf the flexicolor datasheet has push times listed for Portra films and calls for 4:15 for a two stop push. That's probably where I'd start and then you can adjust up/down from there depending on how a test turns out.

Wow! That's a data sheet and a half! 97 pages lol. Thanks for that, I will have a look through it to see what gems I can extract

x1.75 is what my C-41 kit recommends for a 2 stop push. That would be about 6 minutes at 39C. Shadows will get crushed, so aim for compositions that don't rely on details in shadow.

Yeah, that's where I got to, give or take a few seconds. I used time x1.25, x1.25. that is just the calculation of course, I am actually shooting it this evening
