In the world of digital filmmaking and photography, color grading can make or break your final product. One of the most powerful tools to achieve professional-grade visuals is the LUT — or Look-Up Table. But what exactly are LUTs, and how do they help in color grading?
This ultimate guide breaks it all down: what LUTs are, why they matter, and how to use them effectively in your workflow.
What is a LUT?
A LUT (Look-Up Table) is a mathematical formula that maps one color space to another. Think of it as a preset or filter that instantly transforms the color and tone of your image or footage. LUT are often used in color grading to apply a consistent “look” to visuals — whether it’s a cinematic tone, vintage film style, or vibrant HDR punch.
Types of LUTs
There are mainly two types of LUT used in video production:
1D LUTs –
Adjust brightness, contrast, or gamma individually.
3D LUTs –
Modify RGB values across three dimensions for more complex color transformations.
How LUTs Are Used in Color Grading
Color grading is the process of adjusting color, saturation, and contrast to enhance the visual storytelling of a project. LUT simplify this process by giving you a starting point or final polish with just one click.
Here’s how LUTs are commonly used:
- Correcting colors in flat or log footage (like S-Log or V-Log)
- Matching cameras with different color profiles
- Creating mood and style, such as warm tones for romance or teal-orange for action
- Previewing color looks on set with monitor LUTs
