You can photograph almost anywhere in China except at airports, certain bridges and harbours.  Photography at military installations and concentrations of soldiers is not permitted.  Monasteries allow photography but often charge 20-30 Yuan per room per camera.  Tibetans and Chinese are sometimes camera-shy so use your discretion at all times, and when in doubt, ask verbally or by gesture.  Your tour leader and Chinese liaison officer can be of help.

Home video cameras and 8 mm movie cameras are allowed into China, but special permission is needed for 16 mm and 35 mm movie cameras.  Dalai Lama pictures are popular gifts in Tibet and in great demand by the local population. However you should be aware that distribution of these is against Chinese law, and the consequences could be a heavy fine if caught distributing these pictures, not to mention the trouble you will cause for your group and local handling agent.

When taking photos, you must respect Tibetan customs. In some areas, people believe that it is inauspicious to have their photo taken, so ask first for permission of the people you want to photograph. Giving presents sometimes works well to show your friendliness. In some monasteries, it is offensive to take photos, especially photos of statues in the shrine. Sometimes, a certain amount of money should be paid. The amount depends on the popularity of the monastery. Do not take photos secretly in these places. It may bring about unexpected troubles and even be against local regulations. Finally, remember not to take photos in sensitive military areas.
