First post here, as I was directed to this forum from the Darktable (unofficial) FB group.
I picked a particularly bad photo of mine which I shot on the island of St. John a few years ago. The scene at the time was of the sun breaking through a wonderful storm cloud formation. Unfortunately, the vast majority of the image was underexposed and the sun spot itself slightly over-exposed. My intent was to learn how to use parametric+drawn maps in darktable.
I seem to have made a horrible picture slightly better, but wanted to get some ideas on what else I could do, which modules to use, and perhaps gain a better understanding of the theory behind why one chooses specific modules or methods.
Attached are the original, a JPEG of my attempt, and the sidecar file.
