Hi there,

Does anyone know if the procedure to generate the curves for a specific
camera model is still up to date ?

I took the instructions from here (5 years old though) :
https://www.darktable.org/2013/10/about-basecurves/#comment-30544 and in
the README of $darktable_src/tools/basecurve.

I tried to generate curves for my Canon 750d with shots unfocused, both
over and under exposed at the same time as instructed (see the jpg at
https://ibb.co/C29R6Q9).
And well... the generated curve is not very useful... see
https://ibb.co/rG5yvnm

Does one has to do a lot a sample shots (and maybe more diverse kind of
shots) to get a correct result ?
Or maybe someone has successfuly generated its camera's basecurve and can
provide some guidance with this problem ?

Thanks !
