A Smart Album is a virtual album for your images that is based on the certain search criteria with a set of conditional rules. The album is automatically updated when the search criteria are met as well as when the rules no longer meet the criteria. This will help to narrow down a collection of images for a smaller subset to work on and accelerate your workflow. For example, you can use a Smart Album to filter images in a collection that have been rated with three or more stars for retouching.
Smart Albums can be used with a Catalog or Session folders (i.e. Session Folders, Session Albums, and Session Favorites folders).
