Shotwell doesn't write metadata to RAW files, or to the JPEG files associated with those raw files, even if you select the option "Write tags, titles and other metadata to photo files" in the preferences dialog. A solution for the JPEGs is apparently to export them all - at which point the tags are attached
Shotwell does write metadata to JPEG files which do not have an associated RAW file if the option "Write tags, titles and other metadata to photo files" is set. However, in my time of using Shotwell, it has sometimes crashed during writing of metadata and so sometimes omitted to write tags to JPEGs
Given this, I wanted a solution to:
- Write tags from the Shotwell database into RAW files (I have DNG, ORF, CR2 - can't speak for other formats)
- Write tags from the Shotwell database into the JPEG files associated with RAW files
- Write tags from the Shotwell database into JPEG files which were 'stand alone' and not associated with RAW files
- Write tags from the Shotwell database into video files (I have MP4, AVI, LRV, M4V - can't speak for other formats)
This is my solution, build upon a foundation found at https://gist.github.com/iangreenleaf/f6288c6d75103ff28c9145f20539d434
