Automating DNG conversion to save space on a photo server
JPEG and camera raw files can be copied automatically from a card reader into organized folders on a NAS. Keeping years of raw files consumes substantial storage, but converting them to DNG can greatly reduce their size while preserving much of the photo data.
Adobe DNG Converter provides effective , but its graphical interface makes repeated work cumbersome. Its was not suitable for a continuously and isolated desktop workflow.
Existing Docker projects that ran the Windows converter through Wine on Linux were too old to support newer camera profiles. A new was therefore built around a newer Adobe DNG Converter executable.
Key points
- Copy JPEG and raw files automatically from a card reader to a NAS.
- Convert old raw files to DNG instead of deleting them.
- Use an environment to avoid repeated work in a graphical interface.
- Build a newer when existing projects lack current camera profiles.
- Use Wine to run Adobe's Windows converter on Linux.
