Never realy looked into this before and what I'm seeing happen looks wrong. Tried to apply some CC to opening of shot as subject moves from one type of lighting into another. Applied CC to first frame and got it looking OK, moved along TL to where WB looks OK and added a keyframe with no CC. Now as I move between the two keyframes what I'd expect to happen is the gain of each color wheel to reduce which it does but also the angle rotates about 90 deg, much like a set a planes circling to land.
I've tried changing the type of keyframes but don't seem to be able to stop the rotation.
I don't fully understand all the nuances of CC so maybe what's happening is correct but it doesn't seem right to me.
