Chalk and Charcoal
 
 
 

The Chalk & Charcoal effect draws the image onto a solid mid-grey background, translating the dark areas of the image into coarse charcoal strokes and the light areas into coarse chalk strokes.

By default, this effect produces a monochrome (grey-scale) image.

Name

Opacity

Sets the opacity of the effect over the input image. A value of 0 makes the effect completely transparent, while a value of 100 makes it completely opaque.
