DNG vs Native RAW Link to heading
It’s best to use the native RAW format for your camera instead of converting to DNG on import.
- DNG is supposed to convert lossless-ly, but native raw formats are not well documented.
- Special photo processing software from the camera maker requires the native format.
- Most native raw formats support lossless compression (a key benefit of DNG).
- Few cameras understand or save to DNG. Even then they often add extensions which requires special support (e.g. iPhone and ProRes)
- Embedding the metadata instead of using an
.xmp
sidecar file makes it difficult to ensure the photo is exactly the same as it was from the camera. It also makes it very annoying to use with file syncing software which does not properly diff binary file changes. E.g. a network file share to a NAS does significantly more work when managing the photos.
