Please note: Any adjustments applied to an image are forward compatible but not backwards.
An image with adjustments made in Capture One 21 can be upgraded to Capture One 22.
If you share an EIP file adjusted in Capture One 22 with someone running Capture One 21, they won't see the adjustments you applied.
It is recommended that you run the same version of the software.
When sharing EIP files, catalog users can also benefit from EIP export for simplified file sharing of RAW's including settings.
In the Export originals panel (File -> Export Images -> Originals -> Options), you will find an option Export as EIP.
Although EIP files can be imported into a Catalog, with or without any previous adjustments applied like in a Session, EIP files cannot be unpacked in a Catalog. It is therefore recommended that EIP files are unpacked before using them in a Catalog or that they continue to be handled in a Session.
Sessions users can also choose Export originals as EIP files. In both cases, this creates a workflow where the original RAW file and adjustments are copied and exported as a single EIP file.
