Photo of person to fine, detailed line drawing - Xogroroth - 11-28-2023

Greetings all:

Been looking for answer on various sites, but all the results turn out to be very thick lined, and undetailed.
Tried to figure out a way to get far thinner lines, while at the same time, add far more detail.
This is what I generally get:

but this is what I am looking for at the bare minimum:
[Image: 6a64e7a18561b6d1660beea1fb89554e2d812a19_2000x2000.webp]

Preferably even more detailed, with all the hair strains showing.

Nowhere did I find a good tutorial for this, although, I read, there is an automation for this, a plugin, but the author did not speak of how it was called.

If anyone can help me out, please?

Thank you.
Xog.

As with most things graphical it all depends on the original image, never any hard-n-fast rules.

What you can try is starting off with the gimp_gmic_qt plugin - http://www.gmic.eu - the example uses the Artistic > Illustration Look (there are others) to get a smoothed effect. 

Then the Gimp Destaturate -> Color to Gray using a small radius, about 24 (default is 300)

Do this search


And it'll lead you to some YT tutorials
Would that help?

I agree with rich2005, it will depend a lot on the original image.

There are steps that give good results with one image but not with others.

I tried but didn't get anything close to the result you want.

I searched for your second image posted here on the forum. My idea was to find the original image and work on it in order to achieve the result you posted.

I ended up finding your image on an AI website, generated with the following prompt: "highly detailed pencil sketch portrait of a beautiful woman with blonde hair".

Perhaps using an AI website is an option.

Photo from free site (https://jooinn.com/smiling-girl-portrait.html). This is what I tried : 
Colours / Desaturate / Mono Mixer
GMic-Qt / Testing / Photocomix / Graphic Boost-Old
Copy layer 
Filters / Edge-Detect / Edge
Colours / Invert
Opacity layer 25%
Try also different layer modes in combination with layer opacity.

With regular Gimp: Filters > Edge-Detect > Edge, and Colors > Invert

Try Colours / Desaturate / Colour to grey. This is at default.
