One of the more powerful features of Lightroom is the way it brings your photos front and center to you. No shuffling palettes, moving windows, or anything like that. There are panels however and sometimes they may clutter your view of the photo. If this happens and you just want to see your photo, with nothing else then press the L key. This takes you to Lights Dim mode. That means you can still see the interface but it’s very dim and non-obtrusive. Now, if you want to see your photo up against a black background with absolutely nothing else around then press L again to go to Lights Out mode. This hides everything. To get back to the regular view just press the L key once again and you’ll be back to the way things were when you started out. Have a great pre-Christmas weekend everyone!
