Foto Sketcher provides access to those filters in real time. The user loads a picture from his computer and the software will display the original image on the left and a preview of the resulting image on the right. Effects range from Pencil Sketch that you see in the picture below to pen & ink sketches and paintings.

Each effect comes with a few sliders that manipulate settings like Edge intensity, Color Blending or how dark / light the resulting image should be.

The results look incredible if you play around with the sliders for a while. The default settings produced for instance a mediocre pencil sketch of a person but after playing around with the settings for a while the result was astonishing.
