Last update: April 27, 2026

CREATED FOR:

Unsharp-mask. Unsharp masks the layer or the final view image, after all scaling, if layer=comp.

The parameters are applied as is, regardless of whether down sampling has occurred.

op_usmR= *amount*[, *radiusR*[, *threshold*[, *monochrome*]]]

amount

Filter strength factor (real 0…5).

radiusR

Filter kernel radius in pixels (real 0…250).

threshold

Filter threshold level (int 0…255).

monochrome

Set to 0 to apply to each color component separately or to 1 to apply only to the image brightness (intensity).

monochrome is ignored for grayscale images.

The layer mask or composite mask is sharpened as well.

Layer attribute or view attribute. Applies to the current layer or to the final view image if layer=comp. Effect layers ignore it.

op_usmR=0,0,0,0 for no unsharp-masking effect.
