The "Done" button in Camera Raw 8.3 is not applying edited changes to XMP data. For example, edit an image in Camera Raw, hit "Done." Re-open image later and the image is back in its default, unedited state. Image location has not changed in finder -- accompanying XMP file is right there.
The "Open Image" works as it should, both immediately, and if image is re-opened later.
The "Save Image" button also does NOT save XMP data or edited changes. Is there any troubleshooting or solution to this issue?
Photoshop CC, Mac OS 10.9.1.
I can't help you troubleshoot your issue because I don't subscribe to CC, but you should update your ACR plug-in to the current version, which is 8.3.
Don't know about the Done button problem, clicking it it has always applied the changes in the XMP sidecar file and exited ACR for my system.
However, the Save button causes a file to be exported with all changes embedded in the image data (jpeg or tiff), no XMP data is saved in the exported file and no XMP data is modified on the local system, so your observed action is correct.
