Earlier quoted context omitted.
A wedding is one of the most fundamentally public events that have ever existed. The purpose is so that as many people as possible should know that these people are taken. Asking guests to not take photos is such a faux pass that the couple has destroyed their reputation completely. They can have a quiet and private ceremony instead if they have stage fright.
The traditional purpose of the wedding was meeting and joining of families. The "as many people as possible" knowing about it was not a consideration all that much. > They can have a quiet and private ceremony instead if they have stage fright. That would be called "a wedding".
> That would be called "a wedding".
That would be called a secret wedding, a very popular trope in old romance novels.
