Thing I like about Lightroom is the editing is non-destructive. But then, I don't have the capabilities of shooting in RAW. My camera shoots JPEGs, thus I can edit to my hearts content in Lightroom and not need to redo original edits to the original file and save it to another file when I want to change an edit. Example, I process a photo and save the edit. Later, I want to desaturate to black and white, or sepia, or some other different edit, I don't have to use the already compressed twice now file or do my original edits first to the original before making the 2nd edit.
