GNOME Bugzilla – Bug 790844
Support RAW photos when navigating forward/back
Last modified: 2018-04-04 14:04:52 UTC
Currently, RAW photos are displayed only one-by-one (using the embedded JPEG previews that all cameras save), but pressing forward/back arrows doesn't work - probably because raw file extensions are not recognized.
Please support most common RAW file extensions for collections/navigation.
These are at least CR2, CRW, NEF, PEF, DNG (as well as lowercase variants)
That is a really long standing usability issue for photographers on Linux. Thanks!
Selecting the files to add to the collection (and thus allowing Next/Prev) is not handled by file extension but through the mime type GIO reports for them. The list of supported mime types is determined by the list of installed loaders for gdk-pixbuf.
If you don't get the other RAW images added to your collection you'll have to install a loader that supports them. libopenraw ships one for example.
Without such a loader showing RAW files may work in formats that use the basic structure of TIFF files, like CR2.
Thanks for taking the time to report this.
