Originally posted by Blueline54 I've never been asked to save a RAW file after editing in Elements 9, and I always use PEF. You didn't say what model camera you have, but if it's the K-5 you'll need to run the update utility to download the latest version of ACR. To answer your last question, I consider a RAW file to be a negative, and never save any changes to it.
The camera is K20D.
As far as saving the edited version of the raw file, on the bottom left of the screen is the button to "save image" which saves the edited version and not the original. At first I was using this button, but now see that if I use the "open image" on the bottom right, it doesn't touch the original raw file, and opens a copy in the standard editor.
I think I have this all sorted now - thanks for all the help!
