In order to put the emphasis on the image and not on the interface in Lightroom tap the “L” key to enter Lights Dim mode. Tap it again to toggle to Lights Out. Tapping it again will toggle back to Normal mode. To toggle in the other direction add the Shift key. Choose to set the “Dim” level in Preferences > Interface to 50, 70, 80 or 90 percent.
