How do you politely tell your guests that cell phones aren't allowed during the ceremony? You can disagree with me wanting this for my wedding, but I'm going to be paying good money for a professional to take pictures of my big day. The last thing I want is to see a bunch of people with their phones out or even getting in the way of my photographer. During the reception, guests can do whatever they wish with their phones, but I do not want cell phones during the ceremony.
