You can create a variety of Smart Albums based on specific conditions. When created, any image that fits the criteria will automatically be added to the Smart Album. You can create Smart Albums based on such categories as the date, a specific description, Face tags, file names, keywords, camera models, shutter speed, and more. Each category includes a condition, such as "Photos is RAW" or "Camera Model is iPhone 6."
- With the Photos app on OS X Yosemite open, select the "Albums" from the list of tabs at the top of the screen.
- Click on the plus (+) icon in the upper right corner of the Photos app.
- Select "Smart Album" from the drop down menu.
- Name the new Smart Album. It is a good idea to name the album after the action it will be based on. For example, "Edited Pictures" or "iPhone Photos."
- Select the condition you wish the Smart Album to produce. You can include multiple conditions. For example, "Camera Model is iPhone 6" combined with "Photo is Favorite" will aggregate all photos taken with an iPhone 6 that have been favorited.
- When you are happy with the conditions you have set, click "OK."
Note: If the Smart Album did not produce the results you were looking for, you can adjust the conditions by selecting the gear icon under it in the Albums view.
