I would try the g'mic plugin from http://www.gmic.eu and the color curves filter.
The interface looks like this https://i.imgur.com/mtSA5Xx.jpg
Using the HSV option and pulling the Saturation curve right down and adjusting the Value curve gets this https://i.imgur.com/wyqVQrp.jpg
Not as many colors as I would like but getting there: https://i.imgur.com/m0LSawF.jpg
Ah, I assumed (because I hadn't analysed it) that it was simply a monochrome of 256 colours max but obviously not.
I'll try those methods you've listed.
Many thanks,
Jules

- Click Master
- Decrease saturation a lot (-88 here)
- Possibly shift the Hue a bit
Cool, nice transformation.
Thanks,
Jules

Apply the image as a grayscale layermask to two different coloured layers...
The vignette effect was done by making a blurred duplicate of the duotoned image and blending it with the original via a vignette shaped layermask.
First of all, I thought it was a duotone but apparently, it isn't. I tried to replicate the duotone colour in Darktable but it wasn't coming out very well.
You share an interesting technique, I'll give it a try, thanks.
