On 11/11/11, Gerald Donovan aimed his Canon 5D Mark II and 14mm f/2.8 at Downtown Dubai and set it to shoot one photograph every 30 seconds. He left it there for 24 hours, and then took the 2880 photographs and turned them into this beautiful time-lapse showing the passing of a day. What’s neat is that the reflection of the sun and moon can be seen going up and down the Burj Khalifa, the tallest building in the world.
the light going down the Burj Khalifa at the start of the video [you can see the light line going down through the whole tower] is a reflection of the full moon setting. Later in the video, you can see the sun reflection doing the same thing as it sets.
