Bug ID: 432630 Summary: Low-contrast display of 8-bit images Product: gwenview Version: Other (add details in bug description) Platform: Ubuntu Packages OS: Linux Status: REPORTED Severity: major Priority: NOR Component: general Assignee: gwenview-bugs-n...@kde.org Reporter: ferenc...@gmail.com Target Milestone: --- SUMMARY The color management of Gwenview results in image having lower contrast images. The problem persists for several years, over several Cannon cameras used (Cannon 30D, 10D, 5D), and several different RAW converters. 16 bit images were always working well, and I used to think that 8 bit images are just that worse and continued to export only 16-bit images, until I found that the very simple and stupid basic windows image browser shipped with Windows 7 can show the colors I wanted to see on my images even on 8-bit photos. The images are also showing well in Google Chrome, Firefox, Geegie image viewer. Example: https://ferenci84.s3.amazonaws.com/Compare_JPG_Exported.png STEPS TO REPRODUCE 1. Use the images: https://ferenci84.s3.amazonaws.com/Gwenview_Bug.zip 2. Open the same image with chrome or any other browser, or in Windows image viewer and compare with one opened with gwenview. 3. Compare the colors OBSERVED RESULT The colors shown by gwenview is different, especially the contrast is much lower. EXPECTED RESULT The colors should be the same as other viewers SOFTWARE/OS VERSIONS Linux/KDE Plasma: Ubuntu 18.04.5 (available in About System) KDE Plasma Version: 5.12.9 KDE Frameworks Version: 5.44.0 Qt Version: 5.9.5 -- You are receiving this mail because: You are watching all bug changes.
