What is Color Correction?
Color correction adjusts exposure, white balance, contrast, and channel balance to create a technically consistent image or sequence. It generally addresses capture errors before creative styling.
How Color Correction works
Correction normalizes captured material so neutral objects, skin tones, exposure, and shots agree under a defined viewing transform. Controls may operate on lift, gamma, gain, curves, channel matrices, or scene-linear values, with scopes providing measurements beyond visual judgment. It differs from grading because its primary goal is technical balance and shot matching rather than a deliberate look. Corrected masters then feed editorial finishing, grading, compositing, and distribution conversions.
Key facts
- A histogram can reveal clipping and overall level distribution, while waveform and vectorscope displays retain spatial or chroma information that a histogram alone cannot show.
- White-balance adjustment is not merely lowering an obvious color channel; operations in a suitable working space help preserve neutral relationships and highlight behavior.
- Applying correction to transfer-encoded values as though they were scene-linear changes the math of exposure and blending, which can produce different results across tools.
When Color Correction matters
Apply correction before combining footage from different cameras or repairing a color cast caused during capture. Incorrect color-space or transfer-function assumptions can create clipped highlights and inconsistent results.
