So the general rule is that people chewing is not a good photograph. That’s why photographers eat while the guests eat. But this shot is an exception. First, there was a specific run made from the hotel to Reading Terminal Market for the turkey sandwiches. And these turkey sandwiches!
So new rule: when you have turkey sandwiches like these turkey sandwiches, and one of the brides and two of the bridesmaids, in one motion tuck into them, you are allowed to take that shot.
