A first attempt.

Then you start looking into what exactly every slider and whatnot does, and finally try to combine the two. (And yes, as my photo here shows I certainly have a bit left to do about such myself, especially when it comes to astrophoto.) Without such an idea to begin with, well, I guess it's largely a matter of trying stuff to see if you think it makes things look better, and then steel yourself for others disagreeing since it's a largely subjective thing.
