By default AKVIS Sketch converts any image into a black and white pencil sketch. But if the original photo is colored, it is possible to add color from the original image to the pencil drawing.
We use the Sketch plugin in this tutorial, but you can take the standalone edition and use the same parameters to achive this result.
In AliveColors: Effects -> AKVIS -> Sketch;
in Adobe Photoshop: Filter -> AKVIS -> Sketch;
in Corel Paint Shop Pro: Effects -> Plugins -> AKVIS -> Sketch;
in Corel Photo-Paint: Effects -> AKVIS -> Sketch.
Reduce the value of the parameter Midtones Intensity to reduce the intensity of hatching in the uniform light areas of the picture (i.e. the sky).
Also you can use the Color Pencil option in the Strokes section. The result will differ, the option imitates color strokes.
It's possibile to use both ways to add color to pencil drawing (Coloration and Color Pencil).
