An older technique that works well for color grading footage is a gradient map. These apply a tint to your image based on the luminance values of a gradient. Can you mix colors when adding a gradient map? In this movie, author Richard Harrington gives a broad overview of what gradient maps are and how to use them.

- We've spent a lot of time talking about lookup tables,…But there's an older technology…that I like called a gradient map.…A gradient is simply a gradual blend…between two or more colors.…Sort of like the background I'm standing against right now…which is blending from a blue to a green.…However, it's pretty easy to introduce…multiple colors into a gradient.…These colors can be used to strongly tint the image.…Now in the case of a gradient map…that tinting is mapped based upon…the luminosity of the original image.…
When you look at the gradient from left to right…the colors on the left are being mapped…to the shadows, and the colors on the right…are being mapped to the highlights.…This works quite well, and it allows you…to change how the image is tinted or stylized.…And with the introduction of blending modes,…a technique we'll explore in depth in just a bit,…you'll see that the gradient map can be softened…or applied with new creative methods.…This'll give you a ton of flexibility.…Gradient maps are just as easy to create…
In this course, Rich Harrington demystifies lookup tables (LUTs) and shows how to use them with Photoshop, Lightroom, and other Adobe CC applications. He also shows how to use gradient maps—where tints are based on the luminance values in the image—to add creative color and noise to images, and how to organize, store, and share these assets with other Creative Cloud programs and other photo and video professionals.
