Sketches typically are hasty or undetailed drawings or paintings that are not meant to be published as a finished work.
Originally, sketches were freehand creations that would serve as basis for a later and more complex design.
However, currently sketches are also means of entertainment, as users often convert their photos and images to sketches or cartoons in order to make them look funnier or to render them some added originality.
There are numerous software tools that support image to sketch conversion, while also enabling users to adjust various settings according to the preferences.
For instance, a colorful photo could become a black and white sketch, while an old sepia-style picture can get color gradients when converted to a sketch.
