To get a better look at your image in Lightroom you can change the viewing mode in a couple of ways. You can hide the interface using “Lights Dim” or “Lights Out” mode, allowing you to focus on your photograph but still having a quick and easy way back to the displaying the interface. Let’s have a quick look at how to do both.
Below you can see the Lightroom interface with the panels open left and right and below the Image Display area.
Press L on the keyboard. This is the same as Choosing Window > Lights Out > Lights Dim on the menu at the top of the screen. This will darken the interface quite a bit but not completely. Your photograph will not be dimmed.
You can control how dark the interface becomes during “Lights Dim” by choosing Edit > Preferences > Interface (Windows) or Lightroom > Preferences > Interface. From here you can choose 50%, 70%, 80% or 90% depending on how dim you want the area outside the Image Display to be.
Click OK to make any changes on windows, or just click on the red circle at the top left to close the Preferences panel o.
To go to Lights Out mode, just press L a second time and the entire interface except for the Image Display turns black. This is the same as Choosing Window > Lights Out > Lights Out.
Press L again to get back to the default view of the interface.
This is a handy little trick to get the best view of your photographs without any distractions. The L shortcut works in each of the Lightroom modules: Library, Develop, Map, Book, Slideshow, Print and Web.
Another handy tip from Rob Jaudon is, once you’re in Lights Out mode hit the tab key to view your image full image size.
