Sorting an Event by Photo Data
Start in the Library tab.
Click View > Show Photo Data. Now you can see some of the basic Photo Data associated with each subject, If you don't see the option to Show Photo Data there is no data associated with your event yet. If you're not sure how to add data, check out our tutorial on adding data to your event.
Next, click Sort > Sort by Photo Data. This feature will default to using Last Name to alphabetize the event.
There are more options you can experiment with in the View and Sort menus until you find you preferred viewing style.
