Dinasset, I find those images really cute. I love that effect. :clap

Try it yourself, I'm sure you will create very nice outcomes.

Your pics are really great.

Thanks Dragutin.
Which one(s) are you referring to?
Some of my plays became filters anyone can use to produce similar results.

A mini-tut to produce a mosaic (yes, again ! ...) on a limestone.

Block 1
-------
Choose an image with few colours (SOURCE)
example

Block 2
-------
Take a copy of the SOURCE
Convert to Indexed (3 colours)
Back to RGB (OUT 2)

Block 3
-------
Take a copy of OUT 2
On each Colour:
- select by colour
- shrink 1
- apply Mosaic (15, 3, 3, 0.3, 135, 0.3)
At end: created mosaic (OUT 3)

Block 4
-------
Take a copy of OUT 2
Run Difference Of Gaussian (Edge detection)
using default values
Run Colour/Threshold (values 247-255)
Run Erode
At end: Edges (OUT 4)

Block 5
-------
Take a copy of OUT 3
Add as a layer a copy of OUT 4
Run Color White to Alpha (only black edges remain)
Merge down: mosaic completed with edges (OUT 5)

Merge
Run Spread (with value 2)

YOU GOT IT

Thank you so much Dinasset. I'll do your tutorial as I am sure I'll learn something new in effects on photos. :tyspin

Issabella · **Posted:** Thu Oct 19, 2017 9:54 am **(#350)**

Dinasset, I did a PDF file of your tutorial. I added the pattern into the attachment.
I followed it and I got this result. :tyspin

Thanks a lot !

Having participated -unsuccessfully- to a thread related to gradient mapping (GF), I had the opportunity to play again after a while with that nice Gimp feature.
So i'd like to share some of my plays.
The simple procedure I followed is this:
- duplicate the layer
- set it to SoftLight mode
- choose a Gradient
- apply Colours/Map/Gradient Map

It can produce a colourizing effect with the advantage of using different colours for different luminosities.
Examples:

By using gradients with stripes you can get a sort of metallizing look:

Try yourself with different gradients.

For lazy people like me, I also posted a small ancillary filter.

Thank you Dinasset, I'll try your procedure as it seems very interesting. Thanks for sharing.

dinasset · **Posted:** Tue Oct 24, 2017 7:29 am **(#357)**

Looking forward to your experiments, Issa.

Edit: depending on the Gradient you can get any quality of outcome, from horrible to excellent....

My first surprising results

Wow! You have opened the Pandora box. I can't stop testing so many gradients. Here other more results.
