Thanks, Patrice/Issabella. Might try another one soon. Have to pick a good subject to do so, of course. Trick is to create the selection which I then use Mosaic Tile Helper to generate the paths and then stroke said paths with dots. I then feed those dots into G'MIC Skeletonize to create the actual tiles mask. Then use Blend (Shape Average) to colorize (under testing>lylejk; David saved this preset for me when he went another route which didn't do what I wanted).

OK; smoothed out the tiles for Patrice.

This one's for Patrice. lol

Yes; bored on my staycation.

I don't understand
what selection?
what is "Mosaic Tile Helper"?
what dots?
Sorry if I look like a fool, I need a more step by step explanation, or may be it's a bit too for me


Another great one, I love it


Thank you
A different type of tiles, but yes! Excellent as well, it also shows a very good versatility of results with your method

Haven't seen RobA in a while; anyway, he posted a cool script-fu many years ago, Patrice. Need to read through his thread to understand how to use it. It requires a selection before running it. I use various ways to create the selection but lately, I've been using G'MIC's Convolve present and use the select by color GIMP tool to create the selection of the image I'm using.

This is an experiment and I need other people to tell me if this could be a useful technique!

@PixLab,

Thanks for your comments.
What I was trying to achieve was to modify contrast within one masked layer of the luminosity masks without affecting other layers.
The previous example was grossly overdone.

Here is another try for your comments.
