Acerca de esta herramienta
Turn a photograph into a hand-drawn-looking sketch. The pencil and charcoal styles use the classic colour-dodge technique that art software uses, which produces genuine soft shading rather than the hard mechanical outlines a simple edge filter gives.

It controls the blur radius behind the shading. Low values pick up fine detail and produce a scratchy, sketchy look; high values give broad, smooth shading closer to a finished drawing. It only applies to the pencil and charcoal styles.
Turn up Intensity - it controls how dark the lines get while leaving the paper white. Photos with soft, even lighting have fewer edges to find, so a well-lit subject with clear contrast always sketches better.
