Picture the scene - you're stood one end of the aisle, nothing but your nearest and dearest between you and the person you're about to marry, and instead of smiling faces you're confronted with a sea of phones, tablets and cameras. Is this how you want to remember this moment?
If not, you should DEFINITELY consider having an unplugged ceremony.
What is an unplugged ceremony? An unplugged ceremony is where you ask your guests to be in the moment with you and keep their camera devices away. I always recommend unplugged ceremonies to my clients, and I can't stress enough how much of a difference this makes to the emotion in the room when guests are not watching the ceremony from behind a camera.
Take this photo of a very emotional front row of guests at an unplugged ceremony this year - not a dry eye in sight (there were sniffles from tearful guests throughout the whole thing - it was LOVELY):
You may also want to consider if you want your professional photos to include a sea of cameras as you say your vows, have your first kiss, etc. I've even had situations where snap-happy guests have stood in front of me at key moments during the ceremony - not ideal!
If you've picked a wedding photographer who you trust to take beautiful, professional photos, trust that they will cover this part of the day, and request that everyone else enjoys the moment. There is plenty of time for guests to take photos during the rest of the day!
