A photograph represents a single moment in time. So even an honest photo can lie when you don't have enough information.
This Getty photo was passed around last week by the Daily Mail as a peek into a dystopian world where Beijing's only glimpse of the sun comes from digital screens. And yes, the smog is horrible in China right now. But the story is misleading.
In reality, the photo shows a Chinese tourism ad for Shandong province playing on a giant video screen in Tiananmen Square. As the Tech in Asia blog points out, the sun only appears on the screen for a brief period of time as part of a longer ad. The ad also plays year-round, no matter how bad the smog might be.
