It's a terminology thing... because of the way Lightroom edits files (or doesn't, exactly) I can't find the right terminology for what I'm trying to do. Basically, after playing with the settings in 'develop', I want to revert back to the RAW with no "interpretation/manifestation/alteration" and start again. What's this function called? I don't really want to hit "undo" a million times until I'm back to the start. I want to keep the RAW, but delete any changes I made and go back to how it was when I sucked it off the camera.

Thanks

Ah, it's called "reset" thanks! There is a menu item for it under Settings - reset all settings. If you live with Lightroom, this probably seems obvious, but in other programs I've used, the word "revert" or "revert to saved" is far more common.

Now I know ;-)

I will make virtual copies if I want to try processing the same pic different ways... That way I can see what I did to each version.

You know I meant my other left.

Yes you are making perfect since with your interpretation of the digital negative. Like I said, it is my quirky ways that somehow Scott Kelby got me hooked on. I am going to have to try to look up his reason for saying it as it made enough since to me for me to do it but my brain just is not telling me what that really good reason for it is.
