Death From Above: Air Quality Readings

A "Visual Diary of Blue Sky Days in Beijing," shot by Beijing resident Lu Weiwei and her photographer friend Fan Tao, recently received many plaudits from film critics. Beginning in June 2009, the two took a photo of the Beijing sky each day for a full year. In 2009, the Beijing Environmental Protection Bureau announced that 285 days had reached the standard for what the Ministry of Environmental Protection (MEP) calls "blue sky days." But Lu counts only 180 blue-sky days in her photos.
