So my question is: Is there a way of exporting that data from PS so that ACR can use it?
By @StuartKane
Note: This is based on the Adobe Camera Raw plug-in for raw camera data, NOT the Camera Raw Filter for rendered RGB images.
The CRS metadata added when processing the raw file in ACR are stored as metadata in the file opened by Photoshop.
If you then edit the embedded smart object, it uses the original sidecar values which are in the metadata, but it doesn't use the sidecar anymore.
If you then save the raw embedded smart object with new editing settings, the edits are reflected in the smart object, however, they may no longer match the settings stored in the psd container file holding the embedded smart object. If one then edits the previously editied smart object again, the previous edits are used, not the original ones in the container PSD file metadata (which no longer match).
@D Fosse or others... I can't remember where it is getting these edited/updated settings from, as the original sidecar may no longer be accessible. It must be stored in the embedded raw file, which would make sense if a DNG, however with proprietary raw files I don't know...
Anyway, by saving the open/edited embedded raw file from within ACR, the latest CRS settings are embedded in metadata in a rendered file.
So, long story short - depending on where you look, it is possible to view the CRS settings used to process a file.
So, what does this mean?
One can use the CRS metadata to either manually "dial in" edited setting values, or extract the metadata and reformat it as an XMP sidecar file.
Personally, I wouldn't bother, but it is possible.
