Capture One can export DNG files in their original format, however, depending on the support for the file type, some export options may not be available.
DNGs that originate from a number of supported cameras, such as certain models from Leica or Pentax, that write the format natively can be exported in their original format. However, any adjustments or metadata applied in Capture One cannot be included as separate files.
Therefore, if re-imported into Capture One, the originals will be treated as new RAW files with only the default settings applied.
When RAWs from supported cameras are embedded and converted to DNGs, some increased interoperability may be available. In most cases, these DNGs usually have adjustments as separate settings files. Any additional metadata such as keywords or IPTC contact information will typically be embedded.
If settings and other associated files are required with DNG for further use in Capture One (e.g., in collaborations), it is recommended that they are exported in a self-contained EIP package.
Like other source files, Capture One makes virtually identical copies of DNGs in order to preserve the integrity of the originals.
Any supported RAW file, including DNG, can be distributed from Capture One with adjustments, metadata, and any relevant profiles in self-contained EIP files.
