For some reason the comparison site isn't working for me, but it's a moot point. You can't add detail to something that no longer has it by just adding grain.

We all agree on that.

Neither me or Andrea said that you can create new detail by adding grain, what you can do is reveal detail that is there on the DNRed transfer but was not so clearly visible before, the added grain brings it to the surface, creating a perception of increased detail, as I believe that comparison clearly demonstrates.
