Is anybody banning cellphones and/or cameras at their ceremony so that the guests can actually enjoy the moment without having to duck around other guests' electronics in the way of view and so that when you look out to see the happy smiles and tears of joy on their faces you can actually see their faces instead of the electronics? I plan to hire a photographer and videographer for the ceremony and possibly set up an instagram hashtag for the reception so that guests can share their photos from that. Any opinions?
