As the hired photographer at an event, what are your polite ways of turning down personal photo requests? Years ago, if someone handed you their own camera asking, "Do you mind?", it was easy to politely decline with, "I'm sorry, but I'm working right now." Sometimes it's fine for the atmosphere or even quicker to just take the shot for them. Today, however, everyone has a smartphone and the culture at events has changed. Assigned to a shot list and pressed for time, the personal photos can be an obstacle to getting work done. Not to mention, you do it for one person and three other phones are whipped out with eager guests mugging duck face or hand gestures. So, what's your quickest response to focus on the work without coming off rudely?
