LUTs Explained: What They Are, the Types, and How to Use Them Without Wrecking Your Footage
What a LUT actually is, the difference between technical and creative LUTs, why yours looks broken, and the right order of operations so a LUT enhances your grade instead of ruining it.
A LUT can turn flat footage into a cinematic image in one click — or make it look like a bad Instagram filter. The difference is almost never the LUT; it is understanding what a LUT is and where it belongs in your process. Here is the plain-language version, minus the color-science jargon.
What a LUT actually is
LUT stands for Look-Up Table. Think of it as a translation chart: for every color that goes in, the LUT says what color should come out. Feed it your footage and it remaps the colors and contrast according to that chart. It is a preset for color — powerful, but blind. It applies the same translation to every shot regardless of how that shot was exposed or white-balanced, which is exactly why the same LUT can look perfect on one clip and awful on the next.
