My fiance and I recently attended a wedding where we felt like we were surrounded by paparazzi. During the ceremony, while the hired photographer was working his way around the church, guest cameras were going off, which was kind of distracting and at times really obnoxious. We felt bad because the bride and groom were somewhat perturbed. We are hoping to keep our wedding guests from taking photos at the ceremony and just let our hired photographer do his thing because we don't want 20 cameras going off behind us. Is there any way we can do this without upsetting our guests?
