I have a folder full of .dng and .jpeg picture files from a recent trip to France. I just finished editing a bunch of them in Lightroom when I noticed that all of the pictures in the ribbon on the bottom of the screen had ".jpg" extensions. I think I may have just wasted a lot of time editing jpegs instead of the raw files. But the .dng files don't appear as options in that ribbon. Has anyone encountered this problem? If so, how do you get the program to edit the .dng files instead of the jpeg's? I thought that my older version of Lightroom went automatically to the raw files (or in this case, .dng's) when there were multiple formats to choose from.
