Has anyone come across this problem. I have a bunch of files I have processed in camera raw, but when I open them the sharpening is not applied. This wasn't happening yesterday. Is there a bug? Am I missing something?
I threw out the CameraRaw preference file in User>Library>Preferences. That solved the problem
There is a camera raw preference whether to apply sharpening to the on-screen view only, or also to the exported files.
You probably inadvertently set it to screen-only and now after resetting, the default is both.
