The easiest place to choose your favorite images is the Catalog. This is because you can compare images to each other.
In the Gallery View, you can mark a photo as a favorite directly on the image thumbnail. When you hover your mouse over a thumbnail that is unmarked, a small outline of a heart appears in the lower right corner of a thumbnail.
- Click a Shortcut in the Catalog panel or choose a Folder, Subfolder, or Album for the images you want to work with.
- Press the L key ensuring you are in Gallery View mode.
- Adjust the thumbnail size (Small, Medium, Large, or Largest) with the Zoom Controls in the upper left corner so you can easily see image details.
#Click the hollow heart icon in the lower right edge of each thumbnail, The heart can be toggled on or off with each click to mark Favorite or Unmarked.
