@sguyader updated!
I worked on the script again, I set the default opacity of the graphic novel layer to 50%, and I added two more options, so now you can toggle:
- tone mapping
- a slight desaturation
- a vintage toning
Here’s a photo downloaded from pixabay (CC0 Public Domain, https://pixabay.com/en/music-guitar-electric-guitar-sound-890877/):
After running the script, all three options turned OFF:
With tone mapping ON:
With tone mapping + desaturation ON:
And with tone mapping + desaturation + vintage ton ON:
To finish, here’s another neat image (CC0 Public Domain, https://pixabay.com/en/hat-fashion-style-happy-man-591973/):
And after running the script with tone mapping + desaturation, and afterwise turning off the graphic novel layer, and duplicating/masking the detail layer to make the face and clothes grungier:
Pretty cool, isn’t it?
Edit: here’s the updated script:

Updated in the repo. 
Hi Sébastien,
I’d be interested to convert your .scm script directly as a G’MIC filter, if you agree with that idea.
We could then have a filter preview, to see the effect of each parameters directly without having to apply the filter on the whole image. Also, it could hit a larger user base.
What do you think ? I’m not an expert in .scm scripting, so maybe I’ll need help at some point

Hello David,
Sure, that would be nice to have it directly in G’MIC, though I don’t know if you the “high pass” (grain extract/merge layer modes) used in my script can be replicated in G’MIC. I know that using a frequencies layer from wavelet decomposition is similar, but it is not exactly the same it looks, in my opinion, slightly less realistic.

I’m almost sure it can. Those blending modes are also implemented in G’MIC.
I’ll take a look more closely at your script tomorrow and see what I can do.

For those running the current development version of G’MIC 1.8.0_pre, you should be able to access the Sébastien Guyader’s filter which I’ve just converted as a G’MIC filter.
It is located in the category Artistic/, as shown below:
I’ve made the filter parameters a bit more flexible than with the original .scm script (sliders instead of just checkboxes), and there is a working split preview as well.
Please tell me if that is working for you. You need the development version 1.8.0 of the plug-in that you can find here : http://gmic.eu/files/prerelease/
Also, for curious people, here is the piece of G’MIC code I had to write, to convert the original .scm file into a G’MIC filter : http://pastebin.com/Fvf0BDzz
Any feedback is welcome

Thanks David, it works great!
@patdavid awesome. Thanks for sharing again. It’s going on my personal Dokuwiki. I’m only sad I didn’t discover it before processing and posting my comic-con images. I ended up going for a film simulation from RT to get a bit more unique than usual. Have you ever thought of combining everything from beginning of site to 2016 into an epub/pdf and then doing one yearly? Allows people to see them if the net is off or something happens to the site. Your tutorials are awesome and worth saving.
@David_Tschumperle your last post here about the Guyader filter - is that filter in Artistic a filter to automatically do all this in one step?
@Morgan_Hardwood could this be achieved in one go in RT?

I hadn’t considered it before, but now I am! @paperdigits was recently working on a print style for the site as well - I guess we could leverage that to produce something.
Challenge accepted! Though it probably won’t be challenging
Plus it’s digital so no cost to you if only one or two people want it.
I have downloanded the 2.0pre version and the filter work well with gimp. Tanks.
But I like apply it to tif (or png) 16 bit/channel image from command line. I had search in gmic docs but I obtain only transparent file with a vertical bar.
Sorry for bad English
Long time no speak but I thought it intersting to post a few fresh examples with a post/pre version of some shots I took this week on the beatiful island of La Palma.

I’m late to the party, how are you doing this in Gimp 2.10 and G’MIC 2.3.6 ? None of the G’MIC filters mentioned in this article are in 2.3.6.
Are you sure you just don’t need to update your filters list in G’MIC?
