I've gotten two plates (fg and bg) that of course needs to be color matched. Normally I just do it by eye (or sometimes by sampling the black and white point in the grade node), but this time I have been handed color charts shot for each plate at each location in the correct light. How would I use this to match my plates? One idea is to sample the black/white point of the color chart on the fg layer and then use lift/gain to sample the black/white point of the bg layer to get them to match. However this doesn't seem to produce correct results as it feels like you would need the color chart to contain both the brightest and darkest pixels of the plates - which it never does. Also, it doesn't take any of the other color into account. Anyone have an idea? Is there a way to sample more colors than just black and white? I guess you could do it manually by using the Hue-correct tool, but it feels like there would be an automated way that get you close.
best regards, Simon
