Q: On a recent visit to see Michelangelo’s masterpiece I pointed my camera at the beautiful ceiling. Suddenly a guard’s hand blocked it, scaring the hell out of me. What are the rules? TFB, Chicago IL

A: The no photo rule in the chapel is because cameras disturb the religious setting for other visitors. Also, when there are flashes, the bright light can damage the fragile old artwork. Other world art on display, such as in London’s Westminster Abbey, have similar no photo rules. So, when visiting any famous old site, be sure to know where to keep your camera lens closed.
