An Overview of Keywords
Keywords are descriptive words assigned to image versions and saved as metadata. For
example, a family portrait may include such keywords as Portrait, Family, Father, Mother,
Daughter, Husband, Wife, Park, Client Select, Purchased, and more.
Once you have applied keywords to your images, you can have Aperture display an
image’s keywords in the Viewer and Browser. You can also view keywords for selected
images in the Metadata Inspector.
You can use the Query HUD to quickly locate images by their keywords and use Smart
Albums to automatically group images that have specific keywords. For example, you
can create a Smart Album at the Library level named Purchased, which automatically
groups all images with the keyword Purchased. If you want to quickly review the
images your clients bought over time, all you have to do is open the Smart Album
named Purchased.
You can also apply keywords to images based on your future intentions. For example,
you could create a Smart Web Gallery Album that gathers images that have a For web
keyword applied. As you’re reviewing your images, apply the keyword For web to any
image you think is worthy of being published on your website. All images with the
keyword For web are now collected in the Smart Web Gallery Album. If you later change
your mind about publishing an image on your website, you can always remove the
keyword. As soon as you remove the keyword, the image is removed from the Smart
Web Gallery Album.
