Walking in the moonlight


No, this isn't taken on the day. This was actually shot 5:24 am a few days ago. It shows how far current generation of mobile phone's cameras has evolved. I couldn't dream of this few years ago. 


Moonlight consists of mostly sunlight (with little Earthlight) reflected from the parts of the Moon's surface where the Sun's light strikes.


The intensity of moonlight varies greatly depending on the lunar phase, but even the full moon typically provides only about 0.05–0.1 lux illumination.[2] When a full Moon around perigee (a "supermoon") is viewed around upper culmination from the tropics, the illuminance can reach up to 0.32 lux.[2] From Earth, the apparent magnitude of the full Moon is only about 1⁄380,000 that of the Sun.


The Moon's bond albedo is 0.12,[3] meaning only 12% of incident sunlight is reflected from the lunar surface. Moonlight takes approximately 1.26 seconds to reach Earth's surface. Scattered in Earth's atmosphere, moonlight generally increases the brightness of the night sky, reducing contrast between dimmer stars and the background. For this reason, many astronomers usually avoid observing sessions around a full moon.
