I don't think that is possible, but I don't really know. What I am
seeing is one of three possible types of raw conversion -- one with
highlight recovery, one normal, and one mixed. You have to commit these
changes in order to save the file, so I think it is the actual converted
file itself all the way. I think Olympus uses some sort of jpg for the
LCD.
