First thing I do when I begin to work on a picture is deactivate the base
curve. I'd rather start from something as neutral as possible, than to make
modifications/corrections over something that is made automatically and
whose effect I don't like.
Then I use the tone curve to make the modifications I want, and that are
different for each picture.
