Macbeth chart

You hold the chart in front of the camera, take a reference shot, and later in the grading session, you're not fumbling around in the dark trying to figure out what the skin tones actually were. That's the core idea: a 24-patch color reference chart with standardized grays, primary, and secondary colors—precisely defined, reproducible, and irrefutable. The Macbeth chart (or ColorChecker, as it's often called in English) is your digital memory for the lighting situation and camera calibration in your raw footage.

In a practical workflow: You light the scene, set the white balance—and before you shoot the first take, you hold the chart in the light for about 2–3 seconds. No wild movement, stable angle, so the patches are evenly illuminated. The best moment is immediately after the setup, before the lighting situation changes or an actor leaves their mark. Some DoPs also take reference shots between takes if the light or angle has shifted—sounds pedantic, but it saves hours of uncertainty later in the grading process.

The 24 patches follow a standard (DigitalRGB, Kodachrome, or similar industry norms). Six shades of gray from pure white to deep black—this allows you to check the exposure curve later and see if your highlights are blown out or your blacks are crushed. The color patches help the colorist neutralize or consciously preserve the dominant color casts of the lighting situation. In the DCI world and for digital cinema, the chart is practically mandatory; even in commercials and documentaries where color consistency is crucial.

Caution: The chart must be clean and not faded. I've seen enough old charts that were bleached out by the sun—completely worthless. Store them flat, pack them properly. And another practical tip: always hold the chart under the same light as your actors—not in backlight, not in the shadow of the crane. It's not a prop, it's a data point, and only then is it useful for grading.
