LUTs in CGI

LUTs (Look-Up Tables) in CGI are tools that help color-correct or stylize digital images and videos efficiently. Think of a LUT as a baking recipe that maps original colors to new, adjusted colors, allowing artists to achieve consistent artistic looks or moods across scenes. They speed up the coloring process by applying predefined color transformations, ensuring visual coherence and style without manually tweaking every frame. Essentially, LUTs are an essential part of digital post-production, enabling filmmakers and artists to give their visuals the desired tone or atmosphere quickly and precisely.
