Mask Feather or Density: Which Photo Retouch Control Should You Change?
By ImgHeal · Updated
Feather changes the softness of a mask boundary, while density changes how strongly the mask hides content. They solve different problems. Use feather for an appropriate transition and density only when you deliberately want previously hidden material to show through. Inspect the composite and the mask itself before accepting a repair in a separate editor.

Describe the visible defect
Check whether the repair has a hard seam, a broad halo, or too much of the underlying defect showing. Inspect the mask in grayscale or overlay as well as the full image. A seam can arise from tone or misalignment rather than insufficient feather. Do not immediately soften the entire mask, because the same change can blur a correct edge around an eye or a printed border elsewhere in the project.
Test one control at a time
On a duplicate project in an editor offering these controls, make a small feather change and toggle it to see where the transition expands. Return to the baseline before testing density. Photopea's mask documentation distinguishes density from the added blur of feathering. Reducing density can expose a source scratch or rejected generated detail throughout the hidden area, not merely improve the edge. Keep the intended role of the mask visible during each comparison.
Check both sensitive and ordinary edges
Review hair, fabric seams, inscriptions, and empty background at useful enlargement and normal viewing size. A transition that hides a background repair may be unsuitable beside a face. Use local mask editing where one global value cannot suit the whole boundary. Save the editable mask, record meaningful compromises, and export a separate viewing copy. A blended appearance should preserve supported structure rather than conceal a poorly aligned or invented repair.
Before you accept this working copy
- The problem is seam, exposure, or alignment—not assumed blur.
- Feather and density were tested separately.
- Sensitive boundaries remain source-based.

Questions about this restoration task
Can lowering density hide a hard edge?
It may make the composite look different, but it also allows masked content to show through. Diagnose the edge itself before weakening the entire mask.
