Guiding laplacians to restore clipped highlights – #137 by priort – darktable

Well, there’s another problem with that module: it uses the raw white point after the white balance module. And in most cases, esp. red can have a WB coëfficient > 2. So with a 14-bit raw file, you consider a red value that uses 15 bits as clipped, where it isn’t clipped in the raw data before WB. The same can happen with the blue channel.
(Have a look at some clipped areas with WB module on and off, quite revealing…)

A lot of flowers have colours in the yellow-red-violet/magenta range. I really wouldn’t like automatic “correction” of magenta hues for my wild orchids.
