C-41 developer tweak?

I have a large amount of Kodak Hawkeye 400 surveillance film, essentially the same as Kodak HD 400. However, when I develop it, scans of the negatives show a strong red bias in the positive scan. Analog prints confirm this.

Is there anything I can do to adjust the C41 developer so that there is relatively less development in the layer(s) that give rise to red on the positive? I have probably 2,000 feet of this film, so I am willing to experiment a bit if I can achieve a formula that would give rise to a more balanced result.

Do you have a raw or flat/uncorrected scan example?

Are you saying the cyan (red positive) layer is too dense?

I remember from the Flexicolor clone thread, there was this "Notes: BUT whatever you do, pH has to be above 10.11 (measured with my unit 10.13), there is absolutely no chance to get a proper developed film with lower pH! Red will suffer badly!"

Athiril, I was thinking the same. Yes, it must be the cyan layer as it is red in the positive that is excessive. I'll try to see if I can post a scan. I was wondering if I should lower the pH a bit and see what happens.

If you underdevelop the cyan layer, two things will happen: its contrast will be lower, and its photographic speed will drop. Before you go medevial on this cyan layer, try to find out, whether red is too contrasty, or whether it is too fast, too. Lowering pH will help only if it is both too fast and too contrasty.

Quick question... I learned to be careful agitating B&W. I know C-41 needs more continuous agitation when developing by hand.
I should still avoid shaking it like a cocktail, right?

Well, if happens to be that you would do so, I would definitely give a thumbs up for that video!

I have had my first attempt with tetenal yesterday.
3 inversion every 15 seconds and I have went for the rotary development timing suggestion. Plus 15 seconds continuous for the first round of dev/bleach/stab.
Colorwise I am happy with the result !
