Having practiced the process on some pictures, I have written this tutorial. I'd love if someone finds it nice to practice it.
Also, it'd be gratifying to see his/her results in this thread.

This short but very satisfying drawing effect comes from an old script. Dinasset
recently revisited it and with the new “image gradient” function in Gimp 2.10, the
result is better. He gave me his hint for this drawing process.
I’m going to try to explain the process the clearest possible as English isn’t my
From this To that The steps for the drawing effect are:
1 – Open an image you would like to transform into a drawing.
If you look at the histogram of the image, you will get a better result at the end if it is
To see the histogram, go to
Colors – Info – Histogram– in
the open window- look at the Mean value, it should be
about 0.5. 2 –
Duplicatethe source image.
3 – Select the upper layer, go to
Filters – Edge-Detect – Image gradient–
Accept the default value. 4 - Set the resultant effect at
Divideas layer mode.
5 - Select the background image layer, go to
Filters – Colours – Curves– pull down to
get darker the image until you find it nice to see. Could be that two points in the curve
gives better result. Try it. 6 – Create a new layer by a click on the left mouse button and choose
New from visible.
7 – Selected New from visible layer, go to
Colors – Value Invert. Your image becomes
quite a lot dark. Don’t worry as It’s correct. 8 – This step it is optional but from my tests, I can say that most of the images get a
much better look if you apply it.
Select the Value Invert Layer go to
Colors – Desaturate – Desaturateand accept. 9 – Selected Value Invert Layer go
Filters – Blur – Gaussian Blur–
Now we apply so much as 1 % of the measure of the image size in width and height.
(As a sample, if your image is 1600 * 1200, we apply a blur of 16 for width and 12 for
height)The one I’m using is
1280 * 850, the blur applied is
Y 8. Accept. 9 – Set the Visible layer at
Soft Light as layer mode. After that, your image gets a nice
Final result I hope you enjoy this drawing effect.
