As for this photo, some remarks:
While taking pictures:
As far as possible, try to avoid photographing into the back light. If you do, try to adjust the exposure to the brightest part of the motive selection. Or look for a place where the brightest parts of the motive selection are hidden by an object in the background. Underexposed photos can still be saved, but with overexposed parts this becomes much more difficult because the necessary image information is missing.
Here is the task of accentuating the main motif, so that the attention of the observer is drawn to that motif. This can be done by light, color or texture. In this example the main motive for me is the old, half rotten tree root, which is partly covered by moss and young green plants.
I have accordingly tried to enhance the subtle illumination of its immediate surroundings and to emphasize the green plants by saturation. Overexposed part of the sky I “cloned” from the other part of the sky with the help of retouch module :
I did that with darktable and how I did that, you can see in history stack from xmp file:
