down to a grayish value.
- The histogram is compressed in a central area , c

Hello Maik, Gilles
please could we work on that ticket ?
For reminder, I can't use the drops in module "Curves" : if I set the black
point on a JPG, it leads to a greyish picture. Moreover, colors are modified

Hi, please can you update me on this one ?
And in "Luminosity" graph, the grey drop should affect only the luminance,
without changing the chrominance !

For reference, the module "Adjust Levels" also have Black/White Drops that work
correctly.
(And the Grey drops does not modifiy the color balance, which is also a nice
one).

Hello @Gilles, I still have issues on this one.
Pointing the Black drop on a dark area adds too mcuh luminosity. which is not
the expected result.
Black drop should set the black point.
Please can you double che
try on the current digikam version ? I'm pretty sure
you'll understand my point.

For black point, if you set 0 instead 42, curves will be compressed. Idem for
212 instead 255 for white point.

OK Maik, let's stay for the moment with the white balance affecting drops.
But anyway Black and White drops result is strange : they compress the
histogram instead of stretching it !
