You can share shooting photos with others for the same collection at the same time. Nice if you are apart on holidays or at dance event or a marriage for instance! When the photo roll is full, the photos become visible by clicking the photo roll icon. Clicking on a photo in the collection enlarges it and it can be saved in your album. You can shoot regular 12 photos, which can be viewed in a collection for a limited time. You can increase the number of photos by purchasing a 24 or 36 photo roll. A notification tells you when the photos will be removed.
