op_usm op-usm

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

The parameters are assumed to apply to the full resolution image and are scaled down when processing a downsampled image.

op_usm= *amount*[, *radius*[, *threshold*[, *monochrome*]]]

Filter strength factor (real 0…5).
Filter kernel radius in pixels (real 0…250).
Filter threshold level (int 0…255).

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. Ignored by effect layers.
