Writing Meta Data To Raw Files In digiKam
Warning
It is generally a good idea to write metadata only into JPG files. If you do want to save metadata for every RAW file - enabling use of sidecar .xmp files is a universally safe method. Writing directly into RAW files is safe for .DNG files, but results may vary with other RAW file formats. Use at your own risk.
