Thank you for all the tips, but I still don't understand what's the difference between the levels and the tone curve. I wish somebody would add to the documentation: * list of modules doing similar jobs * this one is better at this, this one is better at that... I'm just trying to understand and I'm sure I could do a much better PP if I understood what I'm doing -- sknahT vyS ____________________________________________________________________________ darktable user mailing list to unsubscribe send a mail to [email protected]
