How to Turn Down Brightness Behind a Person in Photoshop: Selective Editing Guide

In portrait and product photography, uneven lighting often leaves backgrounds overexposed, pulling attention from the main subject and ruining composition balance. Readers search for ways to fix this because they want professional results without complex workflows or unnatural edits. Common struggles include harsh selection edges, fake brightness shifts, and preserving realistic subject lighting. This guide delivers precise methods to turn down brightness behind a person in Photoshop using adjustment layers, masks, and AI tools, plus a simple WPS AI alternative for quick results.

Step 1: Pop open your image, bang Ctrl+J to duplicate the layer, and boom, your original's safe no matter what.

Step 2: Layer > New Adjustment Layer > Brightness/Contrast, then Ctrl+I to black out the mask so nothing shows up yet.

Step 3: Select > Subject lets the AI grab the person in a flash, then white-brush over them to pop their exposure back in.

Step 4: Grab a soft Brush at 20-30% opacity, feather those edges nice and easy so it blends like it was shot that way.
