Both RawTherapee and darktable have god demoasic for x-trans, what do you think you’re getting from Iridiant?
Demosaicing in RawTherapee is really good, but CA and distortion correction is done perfectly by Iridient. In the end it is only my laziness that let me buy Iridient, and to get even worse I deleted all my RAF files from before 2019
RT is pretty awesome at CA. Anyway, I would have preferred to play with a real raw file. 
Not for xtrans files

out of stupidity and lack of terabytes I deleted all my raw files from before 2019
Sorry, I didn’t the know the camera in this case.
Nice image @Sunhillow! Here is RT 5.7 + GIMP 2.10.12 attempt. The GIMP was used to increase the contrast in the image (To increase the contrast, I used the Screen blend mode on the castle and Multiply blend mode for the forest.)

Well, that’s partly true.
I knew I was going to downscale the image so that the image in the server wouldn’t be so big, thus I decided to make the wavelets processing a bit more harder than usual. That way, after downscaling everything would be as it should.
The final image will be close (close, although not exactly the same) to what you see when looking at the image at 50% size in the preview area, but without the final sharpening: if you want to see a closer (but not yet the very same) preview in RT, then you will need to copy the Post-Resize Sharpening settings into the Sharpening tool. But don’t forget to set Sharpening off before exporting!!!
Moreover, if you want a final image without downscaling the raw resolution, then you will need to keep the Sharpening tool on, turn off the Resize tool, and tweak the wavelet levels settings to a more reasonable levels.
It all depends on what you expect to get in the end. 
Ouch! 
So let me say “when cropped to the nominal size of 4896 x 3264 distortion correction is perfect”
In this case cropping 6 pixels from upper and lower border would remove this.

Which should be done by Iridient, not by RT…

True! I promise, my next PlayRaw contribution will be a real RAW file.
And I want to thank everyone who worked with this photo.
Basically there were two directions:
Natural colours: the castle is gray, the roof is dark gray and sunset was far away. Here I like age’s second edit the most 
Warm colours: simply looks more pleasing to the eyes (my eyes). Here I like danny’s edit most
In this photo it is really hard to remove the blue tint, especially over the trees behind the castle.

Thanks Aurelien Pierre for color balance pickers which do remove color casts automaticaly.

Here’s my go.
Goals:
- Use new darktable 3.0 modules
- Fix color cast
- Preserve highlights
- Keep top-right roof red
- Remove blue hue
- Reduce vignetting
- Boost contrast
- Warm the castle (a little)

It would’ve probably been better with the original raw file. At least on my Fuji X-T2, when I have the raw in darktable, the improved profiled noise reduction is amazing and lens correction is very good. (It’s then possible to choose the type of demosaicing too, which can further improve color or details, depending on the picture.)
