HOWTO |categorise and share your photos
1 Add keywords
Keywords can be added to a photo by two methods. The first is to choose Window > Info. In the window that appears, you can type keywords or phrases. Press ® after each one. You’ll be offered suggestions from previouslyused keywords as you type.
2 The Keyword Manager
Choose Window > Keyword Manager to see all keywords you’ve used. Click one to apply it to the photos you’ve selected, or remove it if already applied. Click Edit Keywords to create or destroy keywords (the latter clearing them from photos, too) and to assign keyboard shortcuts.
3 Share photos on iCloud
You can share photos with other people using albums hosted on iCloud. Select some, choose File > Share > iCloud Photo Sharing, and click New Shared Album. Name it and enter names or addresses of contacts to share it with, and then Create to send the invitation.
4 Subscribe to an album
When someone shares an album with you, you’ll be alerted by email and whatever methods you’ve configured for Photos in the Notifications pane in System Preferences. Open the app, click Shared and double-click Activity to see options to accept or reject the invitation.
5 Shared album settings
Double-click an album in the Shared view to open it. At its top-right is an option to add to it, and a button with a silhouette of a person. Click the latter to check who can view the album, who can add to it, and whether you get notifications for new items and comments.
6 Import shared photos
To keep a copy of shared photos (in case the owner removes them from the shared album), select them, right-click on one of them and then choose Import. Note that if you try to edit a shared photo, you’ll be offered the option to import it to make that possible.
7 Hide photos
A photo can be hidden from the Photos view by right-clicking it and choosing Hide. (It will remain visible in albums to which it has been added.) To unhide a photo, choose View > Show Hidden Photos Album, browse to that album, right-click a photo and choose Unhide.
8 Delete photos
When you right-click a photo and choose Delete, it is hidden on all of your devices. For a short time, it can be recovered by choosing File > Show Recently Deleted. Click photos you want to keep, then Recover, or click the Delete button to properly get rid of them right away.
