Digital project offers new way to protect treasures

Night falls. Waves of pilgrims gradually begin leaving Jokhang Monastery in the old part of Lhasa, capital of the Tibet autonomous region.

Then, Luo Wenhua leads his team to begin another night's work - shooting pictures of glittering Buddha niches in this monastery, one of the holiest places for Tibetans.

Every evening, until midnight, is the only time they get to work on building one of country's most advanced 3-D high-definition image database of cultural relics.
