About your question, I'll offer my opinion.

Doubly emphasize that.

This is something that many people do not understand.

Every edit you make to an image removes or alters some of the original
information in the image. That means that, if the image is important,
it's far better to rescan the image with a different light setting
than to try to "fix" it.

That is to say, if keeping the information in the image is important,
it's better to re-scan it or take another photo with a different light
source/setting.

On the other hand, if your intent is primarily artistic instead, you
may well prefer the effects of editing.
