Default Re: Color Correction

From what I know of lighting for film you typically use color correction to A)balance the color tempature of different sources. and B)Match the film speed.

For instance you have 2 HMI sources and a incandescent source you might use CTB to match the incandescent to the HMI or CTO to do the opposite.

Full CTB Shifts from 3600ish K to 5700ish K
Full CTO Shifts from 5700ish K to 3600ish K

They are available in in 1/4 1/2 3/4 and full. Full obviously doing the full shift and the 1/4 ect doing a partial shift in color tempature.

Another thing to keep in mind is that typically they don't use dimmers in film lighting....they use...crap what are they called...basically pieces of scrim that cut down the light out put...available in singles and doubles. This is meant to keep you from Amber shifting any of your lights.

Another good tool is Neutral density.

Approach the design as you would any other design...but make sure to figure out how its being recorded...is it film? Is it digitial? Is it HD?

If its film that's going to impact what color correction you use based on the film the DP is using.

Digitial you might get a little more leadway but not much.

A lot of the basic design concepts are the same but make sure you research how color tempature is going to affect film and expourse before getting into it.
