Bug ID: 356975
Summary: Nikon 5300 12bit RAW/NEF: wrong white/black level
Product: digikam
Version: 4.12.0
Platform: Ubuntu Packages
URL: http://jonas.freesources.org/digikam/DSC_0542.jpg
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Raw-Workflow
Assignee: digikam-de...@kde.org
Reporter: jo...@freesources.org
Hi,
apparently, digikam sets wrong white/black levels for 12bit RAW/NEF images from
Nikon D5300. Colors are not the same as in the jpg preview at all. Instead, a
dark, green version of the picture is shown. After some research, I found out
that rawtherapee has the same problem. See the following bugreports and forum
posts for more details:
https://code.google.com/p/rawtherapee/issues/detail?id=2569#c1
http://rawtherapee.com/forum/viewtopic.php?f=3&t=5406
The linked comment of issue #2569 provides a workaround for rawtherapee: Set
the RAW black points for all three color channels to '-450' and white-point
correction for RAW white points to '4.00'. Indeed, this works as expected in
rawtherapee.
Unfortunately I don't find corresponding settings in the digikam editor. If
they do exist, can you point me to them?
Reproducible: Always
Steps to Reproduce:
1. Make a 12bit RAW/NEF picture with Nikon D5300 or fetch the example picture
from http://jonas.freesources.org/digikam/DSC_0542.NEF
2. Import this picture into digikam. The preview looks correct as the jpg
preview is used.
3. Open the picture in the editor. For me, it looks like the following:
http://jonas.freesources.org/digikam/DSC_0542.jpg
Actual Results:
The picture is displayed with wrong colors (wrong black points/white points
settings).
Expected Results:
Correct black points/white points should be set for Nikon D5300 12bit RAW/NEF
pictures.
