Find Edges effect

The Find Edges effect identifies the areas of an image that have significant transitions and emphasizes the edges. Edges can appear as dark lines against a white background or colored lines against a black background. With the Find Edges effect applied, images often look like sketches of the original.

Invert

Inverts the image after the edges are found. If Invert isn’t selected, edges appear as dark lines on a white background. If selected, edges appear as bright lines on a black background.

This effect works with 8-bpc color.
