Basic and extended information
The Basic Information pane appears at the bottom of the sidebar, and displays a brief summary of the photos you've selected. If no photos are selected, it displays a summary of the entire collection. You can toggle the display of this pane using the View ▸ Basic Information command.
The map pane appears at the bottom of the sidebar as part of the Basic Information pane, and displays an overview map the photos you've selected.
