The new task I'll show you how to represent a marker's drawing, using a usual photo.

Open firstly the necessary photo in a new window: File - Open (ctrl+o)



Increase its contrast a little, applying next selection: Image - Adjustments - Curves (ctrl+m).



Apply the corresponding filter also: Filter - Artistic - Poster Edges.



Then mark out the background, using the Magic Wand Tool and Polygonal Lasso Tool to make it a little brighter: Image - Adjustments - Brightness/Contrast.



Move off the markings (ctrl+d) and select for this layer next command: Image - Adjustments - Threshold.



We've got too sharp lines, which is why we have to blur them out a little with Filter - Blur - Gaussian Blur.



Copy this layer: Layer - Duplicate Layer (ctrl+j) and move the copy under the basic layer containing the contours. Then process the layer with Filter - Artistic - Cutout.
