Going to the Peking Opera when you visit Beijing is a must. The singing is of course very special, with the high-pitched voices. However, in my opinion, the colorful and elaborate clothes are even more special and nice to take pictures of. Also the movements in combination with the elaborate clothes create interesting lines and shapes.
If you are interested in the history, the roles of the performers, and the visual aspects of Peking Opera please have a look at Wikipedia.
Here you will find an album of some of the pictures I took during a performance. I had taken my general-purpose lens (28-300 mm), which is always good for this type of shoots. There was no way I could have used a flash: annoying, distance, light drop-off. I set the Shutter Speed to make sure that the movements were more or less frozen (1/60sec and 1/100sec), I checked the Aperture to see whether I had enough Depth-of-Field, and the ISO did the rest. A nice memory of a special evening.
