I recently walked along the English coast and captured a nice afternoon sun bursting through the clouds over a scenic setting of a lonely house and lake. Perhaps overambitiously I intentionally under-exposed the image by -3EV, hoping to recover all the details in Darktable. Unfortunately, for my lack of knowledge of Darktable I have not been able to to this well; I managed to obtain some over-processed image that does not look at all natural anymore (XMP attached). While not pleasing visually it shows that a lot of detail remains in the dark parts of the image, so my hope is that some more capable photographers can rescue this image in Darktable.
(Edited to add the JPEG images).
Here is the JPEG straight out of camera (Fuji X-T3):
And my over-processed edit corresponding to the above XMP darktable file:
