Post your G'MIC experiments here. If you can remember the filters you ran to get final image, let us know.

Rodillus + Poster Edge


Rodillus + Poster Edge + Gradient Norm

Took my avatar, ran G'MIC replace color to set white to transparent (color to alpha would have worked too, but you said to do your best to stick with G'MIC; lol), then ran Rodilius and Local contrast Enhancement for 90% of the result. The rest I vaguely remember since it's the nuance required to make the overal glass look but did cheat since part of that required Artshop's Irridesent filter which is one of the few PS filters that work perfectly fine in PSPI. Anyway, some Anisotrophic Smoothing and also a blend of G'MIC a custom preset that I call glaze which I recreating the settings from the actually G'MIC preset should you want to use it (under b/w menu called Sketch).

Edit: I have decided to change the photo to avoid licensing issues.

Add settings to favorites - and you can share your custom settings ...

G'MICed Photo:

I started with this one:



Select Out put mode as New(s) layer.
Apply on Image layer → [G'MIC] Dodge sketch : -gimp_dodgesketch (with Colorize option selected) and set this layer in Soft light mode and 73% opacity.
Apply on Image layer → [G'MIC] GMic Structure Tensors : -gimp_StructureTensors and hide it.
Select this last one layer and apply → [G'MIC] Hue Lighten/Darken : -iain_hue_light_dark with B/W selected. Set this layer in Color mode and 50% opacity.

Now New from visible → Visible

Select Visible and apply → [G'MIC] Local normalization : -gimp_normalize_local.
Select this new layer and apply → [G'MIC] High Pass : -gimp_highpass.
Add to Highpass layer → one layer mask (black) and play as you wish over the face to increase details.

Values:
[G'MIC] Dodge sketch : -gimp_dodgesketch 3,31.8182,23.1818,2,1,0
[G'MIC] GMic Structure Tensors : -gimp_StructureTensors 0.1,0
[G'MIC] Hue Lighten/Darken : -iain_hue_light_dark 0,0,0,0,0,0,0,0,0,0,0,40.8,0,0,0,0,0,0,0,0,255,100,255,0,1
[G'MIC] Local normalization : -gimp_normalize_local 0.2,6,20.28,20,1,3,0
[G'MIC] High Pass : -gimp_highpass 10,2,0,1,0

Layer and result:

Recycled screenshot as Grunge look background.
G'MIC | Artistic | Cubism

Here's the original image. It's my neighbour's cat, actual there's two of them and they are identical.


This one is after running G'Mic's Coloured Pencils with the default settings. I think it looks good. It's under the Artistic tab


And this one is after running Tone Presets with Warm Vintage selected. It's under the Colours tab.

Very nice result and i like that you took care to copy the settings , that are also visible in the screenshoot,
use as gmic output option "new layers" is also the easiest way to grab the equivalent gmic command

That may be often insufficient to find the corresponding setting in the filter (i.e here ,
-iain_hue_light_dark 0,0,0,0,0,0,0,0,0,0,0,40.8,0,0,0,0,0,0,0,0,255,100,255,0,1 ) because several may be hardcoded values that do not correspond to any filter control (because hardcoded )

instead is cool that Gmic plugin may use that from "Local Command" and "Global Command" , just pasting there in the text field ,

and NOT necessarily one by one you may combine in sequence :

example :this part



become

-gimp_dodgesketch 3,31.8182,23.1818,2,1,0
-gimp_StructureTensors 0.1,0
-iain_hue_light_dark 0,0,0,0,0,0,0,0,0,0,0,40.8,0,0,0,0,0,0,0,0,255,100,255,0,1
-gimp_normalize_local 0.2,6,20.28,20,1,3,0
-gimp_highpass 10,2,0,1,0

that is the command to apply that sequence of gmic filters automatically
As a filter with preview but not sliders or controls , that anyway will execute all that sequence as a macro

Instead if you want save the values so could be shared to be reused with the filter
1)...well or you took a screngrab
2) or you save as a fav , copy the fav code
3) I have a script (thank to pajnickj ) to convert as example " -iain_hue_light_dark 0,0,0,0,0,0,0,0,0,0,0,40.8,0,0,0,0,0,0,0,0,255,100,255,0,1" in the corresponding gmic "fav" code.
And another to export all layers using as name their layer name , so practically the setting used are preserved embedded in the exported images .

I started off with this image. Basically what I wanted to do was make one of those fractal big cat images that I've seen from time to time over at DeviantArt.



I didn't have much idea how to do it so I ran the Dream Smoothing filter, which is under Artistic, with the standard settings. The image still didn't look as I wanted so started hunting around and found out about the Rodilius filter, also under artistic. Ran that on the Dream Smoothing layer and after adding some lighting effects and a bit of colour work using curves came up with this image.



I think it still needs some more work, especially to the eyes, but over all I'm quite pleased.
Both the filters are fairly slow to run, several minutes for each one.
Here's a screenshot of the settings for the Rodilius filter.

I really like that caz. Now for some of the tooth bleach...

LOL, yeah I thought they looked a bit grotty.
