LUTs (Look-Up Tables)

Look-Up Tables (LUTs) are toolsets used in various fields, such as computing, photography, and video editing, to simplify complex calculations. They act like a reference chart, where specific inputs are matched with predetermined outputs. For instance, instead of calculating a new color for an image from scratch, software can quickly refer to a LUT to determine how that color should change. This makes processes faster and more consistent, allowing users to achieve desired results efficiently, from color grading in films to data processing in computers.
