Use layer masks to target adjustment or fill layers

Last updated on Oct 27, 2025

Learn to apply color and tonal adjustments to specific areas of your image by painting on an adjustment layer's mask, creating precise non-destructive edits in Adobe Photoshop.

Layer masks work on a simple principle: white reveals and black conceals. Gray areas in the mask create partial transparency, allowing for smooth transitions between adjusted and unadjusted areas. This makes layer masks incredibly versatile for creating subtle, targeted adjustments that enhance specific parts of your image while leaving others untouched.

Remember that you can always refine your masks later by selecting the mask thumbnail and painting with black, white, or gray. This non-destructive approach gives you the flexibility to experiment with different effects without permanently altering your original image.

Create a mask from a selection

Make a selection of the area where you want to apply the adjustment or fill. Use any selection tool like the Marquee, Lasso, or Quick Selection tool.

Select Layer > New Adjustment Layer and select your adjustment type.

The adjustment layer is automatically created based on your selection. White areas (the selection) show the adjustment, while black areas (outside the selection) hide it.

Make your adjustment in the Properties panel. Refine the mask if needed by painting on it with black or white.

Use Color Range to create a precise mask

Select the layer you want to apply an adjustment to.

Select Layer > New Fill Layer and select your adjustment type.

Select the Color Range in the Masks section of the Properties panel.

Select Sampled Colors from the Color Range dialog.

Select the colors in your image that you want to target with the adjustment and adjust the Fuzziness slider to control how many similar colors are included.

Select OK to create a mask based on the selected color range. Fine-tune the mask by painting with black or white if needed.
