Its not rude to ask your guests not to photograph.
So this is a question I get a lot. Is it ok to ask our couples not to photograph our ceromony? ITS OK! As a photographer the one thing that ruins a photograph is if some one is holding a phone or iPad to capture the walk down the Aisle or the Kiss!!!!
We have had many a moment ruined due to this. We cant really do much about it but it is upsetting. You have booked your photographer a lot of pennies to capture these moment and if a guest ruins it then whats the point of us being there?
Its also scientifically proven if your guests are watching the phone instead of whats going on they dont register it! So put your phones down and enjoy the moment! Let us do the work of capturing the moments.
