Make Your Own Custom Loupe View in Lightroom’s Library or Develop Module
When you’re in the Library Grid view, if you double-click on a photo (or click on the Loupe View button in the toolbar), Lightroom displays your photo in the Loupe view, which is a zoomed-in view of the photo. Besides just displaying the photo really big, the Loupe view can display as little (or as much) information about your photo as you’d like. These text overlays appear in the upper-left corner of the Preview area. You’ll spend a lot of time working in the Loupe view, so let’s set up a custom Loupe view that works for you.
Go to the Library module’s Grid view, click on a thumbnail, and press E on your keyboard to jump to the Loupe view (see Figure 1).
