How To Use RGB and LAB Numbers in Adobe Lightroom Classic
Just below the histogram in Lightroom Classic’s Develop module are a set of three numbers that can be useful when optimizing your images. Let’s explore how I use those numbers when evaluating images before processing, when color correcting images and when I need to match the color between two areas. I’ll also attempt to explain the difference between RGB and LAB settings, how to switch between them, and when one option is more useful than the other.

Learn to take the guesswork out of matching colors by using the numbers that appear below the histogram in Lightroom Classic. In this case, I’ll match two different colored bricks on a building, but you could just as easily use this for all sorts of other purposes.
Adobe’s Julianne Kost and Photoshop Cafe’s Colin Smith demonstrate Adobe Lightroom Classic’s new Range Masking. (Remember, what works in Lightroom also works in Camera Raw.) Range Masking, by luminosity or color, is a significant step forward in selective or regional image adjustment during Raw processing.
