Bug ID: 308489
Severity: major
URL: http://http://www.robert-zeller.org/transfer/DSC0607_v

Version: 3.0.0
Priority: NOR
Assignee: digikam-devel at kde.org
Summary: raw image development produces artifacts in digikam
3.0.0-beta 2
Classification: Unclassified
OS: Linux
Reporter: robert.zeller at robert-zeller.org
Hardware: openSUSE RPMs
Status: UNCONFIRMED
Component: Image Editor
Product: digikam
I encountered a strange problem developing a Nikon raw file with
digikam 3.0.0-beta2 which did not occur under digikam 2.9:
Under digikam 3.0.0-beta2 (latest version from git) a pattern of a faint
rectangular lattice of fine lines occurs over the entire .JPG that was
produced from the .NEF file. This does not happen when using digikam
2.9, nor do I see this pattern when developing the raw file by
rawtherapee or darktable.
You may view the results by downloading the original NEF and the JPGs
produced by digikam 2.9 and digikam 3.0.0-beta2 from the following website:
raw-file: www.robert-zeller.org/transfer/DSC0607.NEF
JPG digikam 2.9 : www.robert-zeller.org/transfer/DSC0607_v2-digikam_2.9.JPG
JPG digikam 3.0.0-beta2:
www.robert-zeller.org/transfer/DSC0607_v1-digikam_3.0_beta.JPG
Since the web-page is not open for directory search you have to specify
the full urls when using wget for download.
Caution: the files are huge since they were taken with a NIKON D800
which has a 36 Mpix sensor.
I used the same settings in digikam 2.9 and 3.0.0 when developing the raw.
I am wondering what the reason may be for this unacceptable result in
3.0.0-beta2?
Reproducible: Always
Steps to Reproduce:
1.download test images from web site given in "Details"
2.use digikam image editor to develop Nikon raw image: DSC0607.NEF
3.
Actual Results:
digikam-3.0.0-beta2 produces a faint rectangular lattice across the entire jpg
that is produced by the image editor
Expected Results:
no artifacts !
