How annoying is it when you're standing at the altar and you look out to see all the guests that are sharing your big moment with you, only to be blocked from seeing their smiles by an ocean of mobile-phones?

Or when the groom can't see his bride walking down the aisle because so many of her friends have jumped in the way to get their own 'perfect' photo for Facebook?

Or when you pay a lot of money for a great photographer, but guests are blocking every perfect moment with their phones and tablets?

There is a cure...
