They are carefully designed to produce specific visual effects or corrections. These transformations are based on complex algorithms that have been developed by color scientists, photographers, and filmmakers. By applying a LUT, you can quickly achieve a desired visual style or mood, such as making footage appear warmer, cooler, more cinematic, or vintage. They allow you to modify the color balance, contrast, brightness, and saturation of an image or video.
They are used to manipulate and transform the colors and tones of images or videos in a systematic and consistent way. Look-Up Tables, often abbreviated as LUTs, are essential tools in the world of digital image and video processing.
