What is a 3D LUT?

Antler Post’s Nick Shaw explains a 3D LUT and how Convergent Design’s Odyssey can be used to apply it.

He writes, “A 3D LUT is a way of transforming an image, where any set of red, green and blue values at the input map to a different set of red, green and blue values at the output. Unlike a 1D LUT, where a given red value at the input will always map to the same red value at the output (like Curves in Photoshop) with a 3D LUT, the output value in each channel is affected by the input values in all three channels.”
