In Photos Workbench, keyword palettes and keyboard shortcuts make it particularly easy to assign keywords to your photos. Photos Workbench can filter albums by keywords, allowing you to find or focus on a specific set of images.
Along with albums, keywords help you organize your images. Typically, albums group photos by event. Keywords are labels that describe the subject of a photo or properties of the photo. Examples: “Family”, “Landscape”, …, “Still-Life”, “Action”, …
Keywords can also be used to flag images you intend to work with or export. For instance, you can assign the keyword “Share” to all the photos you plan to add to the family’s shared album.
