Guess the meaning of this sign?

It's worth checking with your priest/registrar that photography is allowed during your ceremony - and spelling out how important your wedding pictures will be to you and your family. In a recent wedding, we weren't allowed to take any pictures at all during the Church service. It's a great shame. All the good photographers we know are very discreet and make every effort to keep a low profile, while getting some great pictures. We managed to catch up at the Reception, of course, but it's a pity not to have photographs of the couple exchanging their vows with all the accompanying emotions.
