You have your camera set to shoot JPG and Raw. The NEF is the raw picture.
It is up to you which one you want to edit but if you are shooting raw that indicates to me you shouold edit the raw or else why would you shoot it?
Each picture is independent so you can tag and star each individually.
Thanks for this
One more question though
When you compare the two images, wide by side, how do you low which is the NEF one? Where does it say so? Is there an indication that I am missing somewhere? Or do you right click the image or what?
If I were you, I would not try putting the two images side by side full screen with F12.
Instead, I would select one of the images and then F11 (that displays one of the two images full-screen) and then with the right and left arrow, switch back and forth.
Or do you right click the image or what?
My answer to this question is always ... right-click on it and find out
You can open Info Panel in the full screen view. It's floating type so you can place it anywhere down the screen and it will keep showing the file in selection <its name for e.g.> in the General header when in Compare Mode (F12).
