Post-production color adjustment — correct exposure, remove color casts, or craft visual mood intentionally. Essential step before final delivery.
The post-processing of color values happens in post-production – where the raw footage gets its final visual identity. On set, we shoot under constantly changing lighting conditions: one scene in morning light, the next under artificial tungsten lamps, then daylight through a window again. The camera sensor or film material captures these differences, but it's only in the editing suite that we bring order to the chaos.
Practically, this works in two movements: Color Timing first stabilizes the technical foundations. We neutralize color casts – such as the orange cast from a tungsten lamp or the magenta cast from an older lens. Exposure is adjusted so that cuts between different shots don't jump. This is necessary, not a creative decision. In DCP mastering or already during online editing – depending on the workflow – we bring the image values into the acceptable range using curves, levels, and color wheels. A good grader works with scopes: histogram, parade, waveform. Not deciding solely on the monitor.
Color Grading comes afterwards – or simultaneously, if the timing already dictates the direction. This is where the emotional aspect is shaped. A scene gets a blue-cyan cast for melancholy, another warm orange-yellow tones for nostalgia or morning hope. This can be subtle – a 10% temperature shift – or radical, like in the extreme color grading aesthetics of the 2010s. The grader works selectively: the shadows get a different color temperature than the highlights, the midtones follow their own logic. Qualifiers (HSL ranges, luma ranges) can isolate individual color areas – adjusting only the green of vegetation while skin tones remain neutral.
The technique varies: During online editing in DaVinci Resolve or similar systems, we work non-linearly and iteratively – shots are treated in the order of the edit, but also in groups simultaneously to maintain consistency. Later in DCP mastering, final LUTs (Look-Up Tables) are generated that define the overall film. A grader needs patience: what looks breathtaking on the grading monitor must also hold up in the cinema and on various displays. Therefore, calibrated monitors and a dark room are not optional.
