iPhoto has had these features for over a year, but although it may appear that they’re only of interest to consumers, Faces and Places metadata can be valuable to professional photographers too. Once Aperture has been properly configured, Faces can help you detect familiar faces in group shots instantly, and Places can be useful when looking for photos spanning years taken in the same location. 

If you don’t use Aperture’s smaller sibling, you may at first be a little confused by how Faces and Places work, so this Masterclass is for you. We’ll show you how to set up each feature. Some cameras have a built-in GPS feature to automatically record a shot’s location, but things can go wrong, so we’ll show you how to edit that information, or create it from scratch if your camera lacks this ability. 

1. Unnamed faces  Click on your Library’s Faces section in the Sidebar. If you’ve never used it before, you’ll be graced with an empty cork board-style theme and a message explaining the function of this new feature. To start using it, click on the Show Unnamed Faces, bottom left of that pane.

2. Naming faces  A series of faces will appear along the bottom. Click on one to rename it. If the name already exists in your Address Book, it’ll pop up as you type and if your Mac has made the correct guess, hit the Return key to set that name for that photo (or keep on typing it if it hasn’t).

3. Snapshots  Repeat the procedure for other photos in the list. Once you’ve done a few, you’ll notice that your cork board fills up with Polaroid-like snapshots of the people’s faces you’ve identified. Mouse across a thumbnail to see all other photos contained within. Hit the Spacebar to set a new main shot.

4. The same person  Double-click on a thumbnail to reveal all photos contained within. By default, those thumbnails show the entire image. If you’d rather just see the specific face, click on the Faces button, bottom left of the interface. To reverse that choice, click on Photos, next to the button you just clicked.
