[Digikam-users] converting Pentax RAW problem

when you load a raw image directly with the editor the gamma is not set,
meaning that the original linear curve of the cameras sensor is used.
You can either shape the lightness correction curve to a convex form
(last tab in the CM dialog). Or, which is easier, use the
Lightness/Contrast/Gamma filter afterwards and set the gamma to a value
usually between 1.8 and 2.2. You may have to enhance the contrast
afterwards. Find your raw image with gamma=2.2 and contrast=80 here:
Btw. I'm of the opinion, that opening a raw in the editor should set
gamma and contrast to a reasonable value by default (or at least ask the
user). I recently reported this as a bug, so I suggest you vote for it:
