What Is Layer Masking?
Easy Guide to Selective Editing, Non-Destructive Workflows & Creative Control
What Is Layer Masking?
Layer masking allows you to hide or reveal specific parts of a layer without permanently erasing anything. Masks use grayscale values: white reveals, black hides, and gray partially reveals.
This technique provides full control over which areas of an edit appear in the final image.
Why Layer Masking Matters
- Non-destructive editing: Changes can be undone anytime.
- Precision: Perfect for blending, retouching, and composites.
- Selective adjustments: Apply effects only where needed.
How Layer Masks Work
The mask overlays the layer. Painting with black hides the area; painting with white reveals it. Shades of gray create partial transparency.
Common Uses
- Selective brightness/contrast edits
- Removing backgrounds
- Blending multiple photos
- Fine-tuning retouching work
Layer Mask Techniques
- Use soft brushes for smooth blending
- Use gradients for natural transitions
- Invert masks for quick adjustments
