THE NEWLY improved AI masking tools in Lightroom Classic and Photoshop CC’s Camera Raw allow you to quickly isolate either a subject or background. There are buttons for each, so all you have to do is click one and a mask will automatically be generated for either area. Once done, you can go on to alter either area using an array of powerful tonal sliders. These include Temperature and Tint sliders that let you selectively alter the white balance in different parts of the frame. You can experiment by selectively shifting the white balance controls for either the subject or backdrop. This could either serve to correct a mismatch between the two, or intentionally create one, as we’ve done here by cooling the backdrop, which helps the subject stand out and improves upon the rather dull original background.
