Stewart posted the picture to his Facebook page, along with an impassioned plea for wedding guests to unplug during ceremonies.
"You're paying a photographer quite a bit of money; that means you want great photos. We cannot do our best work with people getting in our way," he wrote.
"In your invites, tell everyone you're having an unplugged ceremony: no technology, please, Write it on a chalkboard which guests can see as they arrive on the day," he continued. "HIRE A PLANE TO WRITE IT IN THE SKY!"
"And guests, you've been invited to this wedding to share and celebrate the love that two people feel for each other," he concluded. "You are witnesses to their marriage, so for goodness sake, watch them with your eyes and your minds, not your phones."
