Key takeaways 
The selection lets your client mark their favorite photos
You can limit the number of photos to select (10 by default)
Your client validates their selection with you once it's finished
Choose a selection-type or custom gallery and enable the selection to have your clients select your photos.
Enable Limit the selection and indicate the maximum number of photos included (10 by default). Ideal for « X photos included » packages. Without overage allowed (see below), your client cannot exceed this number: it's exactly what is included in their package.
You can let your client choose beyond the included limit:
Allow exceeding the limit: your client can select more than the included number
Show the price of additional photos: display the cost of each extra photo
Price per additional photo: the amount you set (5 € by default)
This way, each photo chosen beyond the limit is counted as an additional photo. Your client sees their number of included photos, the unit price of the extra photos, and the total of the supplement which updates as they make their selection.
Tip: leave the overage without showing a price to offer flexibility, or with a price to automatically sell the extra photos.
When your client has finished, they send you their selection of favorites: you know precisely which photos they chose, and the possible supplement.
