You have the option of creating a virtual copy, or making the master a proof. Unfortunately on one image, I decided to "make this a proof". Is there any way to undo that particular step? I've tried stepping back through history, re-writing the meta-data at that point, then re-reading trying to get back to where I was. When I turn on soft-proofing it reverts to making the master a proof.
Yes I know, but it wasn't completely clear (to me anyway) what was about to occur when I chose that option. I "thought" it was making the adjusted image a proof (another virtual).
