I'm new. I've made changes to NEf files in ACR in the "Basic" panel. I see the little icon in Bridge that indicates that changes have been made to the NEF file. How do I get back to the original NEF file after I've exited the programs, Bridge, Photoshop, etc? I'm using PS CS 5.
In Bridge: Edit, Develop Settings, and Clear Settings. If you are saving the edits in the .xmp sidecar files you can also just delete the file. ACR does not actually modify the raw file, saves edits in either a centralized database or sidecar files.
