Creating LineArt from Photos

To begin, have the target image layer selected, as I have captured above.

Next, go 'Filter/Blur/Smart Bur' as I have captured below.

From the 'Smart Bur' dialog, make sure the 'Edge Only' Mode is selected and toy with the 'Radius'/'Threshold' sliders. The objective is to ensure that an edge line covers the entire image with some overspill into the interior of the image as well.

This will produce a similar result as below.

Next, with the same image layer active, go 'Image/Adjustments/Invert', as I have captured below.

Inverting produces the below resulting image.

The above result is quite satisfactory, but to add to the edge effects of the line art, go 'Filter/Artistic/Cutout' as I have captured below.

Depending on how thick you want the lines, adjust the Cutout sliders for the desired effect.

Here is the final result.
