First, we want you to be present and, in the moment, when we take our vowels. Secondly, we only have the photographer for a few hours and want to ensure we get the most amazing shots of you without your phone in the way. There will be plenty of opportunity for you to show off your photography skills during the reception.
If you don't have a pocket, bra, or bag that will house your phone/camera, you may leave it in your room or the designated 'unplugged' area set up at the ceremony & the social hour.
