Angelo Lorenzo explains LUTs, writing, "A LUT, or look up table, changes color from one value to another based on a list of values. For video and motion graphics, a LUT is useful for matching footage from one source to another (i.e. a 3D render to live action film), for visual effect (i.e. vintage film emulation), or for output preview (i.e. film stock, digital projection, and DVD). While color management for video is still considered the wild west, the use of LUTs has increased as hobbyists and indie filmmakers gain access to once-expensive tools like Adobe Speedgrade (formerly Iridas Speedgrade NX) and Blackmagic DaVinci Resolve."
