Wedding photographers often ask people to refrain from taking photos during the ceremony. It sucks to have every photo that you hired a professional to take have a sea of people holding up cell phones so they can each take their own photo. In this case it's not rude to request that people not take images, it's a practical matter so people can have photos of their wedding instead of photos of people taking photos of their wedding. Much of this wouldn't be necessary if people could just be present at events instead of rigorously chronicling their every experience.
