Dear Mrs. McVeigh,
It had been several years since I attended a wedding, until last weekend. I was very surprised to see everyone get out their cell phones and take pictures, as the bride was walking down the aisle. Do you think this is okay?
I do not think that this is good etiquette. A professional (or designated) photographer was probably present, so the bride and groom did not need anyone else taking pictures. A bride walking down the aisle is one of those moments that friends and family need to watch through their own eyes, and not through their phone camera. Especially in a church, this seems very disrespectful. Wedding ceremonies are formal occasions, no matter what the venue, and photography should wait until after the ceremony.
