What exactly is a Lookup Table? A Lookup Table, or LUT, is a mathematical formula that modifies an image’s color variables. This recovers details, shadows, and highlights. LUTs also expand the color gamut and help you match your shot to a specific color space. In this movie, author Richard Harrington defines what LUTs are and how they are used.
- To get started, let's make sure we have…a good working definition of what is a Look Up Table.…A Look Up Table, or LUT, is essentially a digital file…that's going to make up the difference…between the source file and a destination state.…For example, you might shoot with a color profile…on your camera that records in a flat or a neutral state.…This gives you more information towards the middle…of the histogram, and makes it easier to recover shadows…or highlights during post-production.…
However, applying a Look Up Table can easily remap this…from a flat, or a log state, and expand the color gamut…so it easily matches up with things…like the Rec. 709 Color Space for HD television.…However, one thing that's important to note…is that with Look Up Tables, you're often going to use…other adjustments in between.…A Look Up Table is not necessarily a quick fix.…If the footage wasn't shot properly color balanced…or with other issues, you'll still need to introduce…basic color-correction into the mix.…
However, when you have properly exposed,…
