LUT (Look-Up Table)

A Look-Up Table (LUT) is a digital tool used in image and video processing to quickly change or enhance color and tone. Think of it as a pre-made color recipe stored in a table. When applied, the LUT replaces or modifies the original colors in an image based on the table’s instructions, allowing for consistent color grading or creative effects. This method is efficient because it avoids complex calculations in real-time, making it widely used in photography, filmmaking, and display calibration to achieve desired visual styles quickly and accurately.
