Bug ID: 427350
Summary: digikam dng converter fails to correctly encode white
balance or camera metadata for CR3
Product: digikam
Version: 7.1.0
Platform: Appimage
OS: Linux
Status: REPORTED
Severity: grave
Priority: NOR
Component: Plugin-Bqm-DngConverter
Assignee: digikam-bugs-n...@kde.org
Reporter: charles.fig...@wartburg.edu
Target Milestone: ---
SUMMARY
The white balance for CR3 images converted using the linux digikam 7.1.0 is
corrupted, and image metadata (lens,aperture,ISO,exposure, focal length, etc)
is absent. Images are strongly magenta. Other software (such as darktable)
produces a warning ("failed to read camera white balance information").
Images converted through Adobe Digital Negative Converter 12.4.0.555 on Wine
work as expected.
STEPS TO REPRODUCE
1. Set the checkbox "convert DGN"
2. Import the images
OBSERVED RESULT
CR3 files converted to DGN format have corrupted white balance information.
The JPG preview has a bad white balance. The image metadate is lacking all
camera metadata (lens, aperture, exposure, ISO, etc)
EXPECTED RESULT
The resultant DGN format image should have white balance information that
reflects the image. The white balance and metadata should be able to be read
by other image manipulation programs capable of reading DGN files.
SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux/KDE Plasma: Kubuntu 20.04
(available in About System)
KDE Plasma Version: 5.18.5
KDE Frameworks Version: 5.68.0
Qt Version: 5.12.8
ADDITIONAL INFORMATION
Running Digikam 7.1.0
I have sample images, but as these are raw and DGN image produced by the Canon
R5, these images are 41-45MB in size. How can I submit these?
