Color LUT’s take in color values and give out corresponding colors, some LUT’s increase saturation, others punch contrast and some even change colors entirely. Most of the time they will do a combination of things. No matter how complicated an image may seem, a LUT is simply a process that turns one color into another.
The good thing about LUT’s is they can be used in nearly any program that adjusts color. Because LUT’s work with so many programs, they are more useful than traditional color presets that only work in one app.
Using LUT’s you can do fast overall corrections, punch certain colors or even give your shots a unique filmic style.
