Since I do not want to spoil another thread, here are some very personal ponderings:
The other thread takes for granted that every piece of photography is meant to be a Piece of Art. Oh, no. Far from it. I’d say that most images are intended to document something.
The other thread also advocates that you have to understand maths to be able to use darktable to its full extent. Oh, no. Not at all. You don’t have to be able to quote the square root of three with five decimals to be able to use darktable properly. That has nothing to do with it.
Umpteen years ago, I was responsible for introducing computers in the ad agency world. The AD and his minions were eager to learn; but we approached the tasks in different ways. When the AD wanted to place a headline, he squinted with his eyes, and immediately dragged it into the correct position. When I did it, I brought out my calculator, and then typed in x = -2.5px, y = +6px. Both results were correct, but the AD neither needed any Maths, nor a calculator.
He also swiftly learned that if he dragged a certain slider to the left, the image became darker.
And dragged to the left, the image became lighter. And so on. No maths called for.
