What is colour grading and when do I need it?
Short Answer:
Colour grading is the process of adjusting the colour, contrast, and tone of footage to create a consistent, polished, and intentional look. You need it on virtually any professional video: it balances shots so they match, corrects exposure and white balance, and applies a creative style that sets the mood. It is what makes footage look "cinematic" rather than raw.
Overview
Colour grading has two jobs: technical correction (making every shot consistent and accurate) and creative styling (giving the film a mood and identity). Almost all professional video benefits, though the degree of grading varies by project.
Detailed Explanation
What colour grading does
Colour correction: balances exposure, white balance, and contrast so shots match.
Consistency: makes footage from different cameras, lenses, and times of day feel unified.
Creative look: applies a mood — warm, cool, punchy, or muted — that supports the story.
Focus: guides the viewer''s eye and reinforces brand colour.
Modern cameras often shoot in a flat or "log" profile that looks washed out until graded, so grading is a required finishing step rather than an optional luxury. The colourist works from the locked edit, protecting the highlight and shadow detail captured on the shoot.
Example
Footage from a bright exterior and a dim interior can look jarringly different straight out of the camera; grading brings them into a consistent look so the film feels like one cohesive piece rather than a collection of clips.
