Layered Color Correction

[Harry Clark]

OK, here's a workflow conundrum for multi-camera shows.
Since all cameras are like snowflakes (no two are alike) and there is no live "paintbox" grading with Red One (RAW-style capture)...
First off, it might be useful to have a software Macbeth and 11-step grey scale and Stouffer scale built in to Redcine so if you shoot one in the field you can do some quick and consistent matching.
You would normally first be concerned with "matching" cameras and then achieving your look. Soooo... on a 3-camera Red shoot, I would first think to shoot a grey scale under a neutral light, and then shot your scene. In Redcine, you would ideally set up the "A" camera to the grey scale, then the "B" camera, etc. So now they all match as far as the slight differences in sensors, circuits, lenses go. But now you dial in a "look" on "A" camera and save it. Is there a way to save a bottom layer of correction for each camera so they "match", and then an upper layer of correction for the "look"? As far as I can tell, once you dial in your "look" and save it, you can apply it to other shots. But I assume that it overrides any other correction to the shot you're applying it to.
Apologies; it's late and I'm not sure I'm explaining it correctly. And it's probably outside of what Redcine is meant to do. More like what you'd do in a DaVinci suite. But it would be great if there was a fast efficient way of doing this.
Cheers,

Makes sense... 1x look matches all cameras say B and C to A

then another is applied to A+B+C which is the grade look.

Dunno but on a multi camera shoot I'd worry about that stuff later and shoot.

Its all raw so its all good to go and match grade later.

I mean they cant be that far off.. can they? :-/

I agree that you worry about it later. I just wondered if having the camera "match" built in to the look would save a bunch of time in the grading process...
Maybe Red's QC is high enough that matching will truly be a thing of the past...
Anyone done any multi-camera shoots yet?
Cheers,

The trick is both systems involve a match.

If you try to match all cameras before the grade you'll have to do that manually.

If you try to match all cameras after the grade you'll have to do that manually.

I understand the desire to be able to just bulk apply a correction to lots of shots. But both approaches require human interference for a match so I don't see too much point in pre-matching except for later changes.

I don't see a consistency problem across RED cameras.
