Sharpening techniques (lizard subject)

I am a scientist myself and work with images mainly in high-resolution microscopy.
If I don’t photograph professionally, I do so only from the “artistic” aspect, the accuracy of the reproduction plays hardly any role for me.
The possibilities of post-processing in digital photography make it very difficult for me to find the boundary between necessary improvement and unwanted change of “reality”.
Nevertheless, I would like to show a technique that I sometimes use to “sharpen” and make fine details more visible.
However, this use of tone mapping is not really suitable for scientific photography.

Only one color cuvre in darktable plus (right) and minus (left) tone mapping.
