Photographer David Gray went back to the Bird’s Nest on Tuesday to see if indeed there had been any improvement in the air quality, from a visiblity perspective at least, since the last time he took a picture from the same position. Top is the June 9 and bottom July 8. The result of the Gray Test? Marginally better.
