it is the same color temp as daylight. it only looks blue...

its the Purkinje effect.. our eyes are more sensitive to the shorter wavelength colors. such as blue. so in the dim moonlight we SEEM to see more blue. even though it is the same color as daylight. that is why we light night scenes slightly blue.

hope this makes sense.

Think of the moon as a big 18% gray rock reflecting sunlight, and you come pretty close. ;) In other words, the color is pretty close to daylight.

What surprises alot of people is that to capture details on the surface of the moon (i.e., see the "man in the moon"), you would use the same exposure you would use for a sunlit scene in midday.

This discussion brings to mind a happy event. I just attended the 40th Kodak anniversary of a colleague who now works on Kodak motion-picture film and digital projects and SMPTE and ISO standards activities. His first Kodak project was working on the Lunar Orbiters, which orbited the moon to take close-up photos to map its entire surface in preparation for the manned exploration by astronauts. A remarkable achievement --- the film was processed in space, scanned, digitized and the signal sent to earth for recovery of the detailed images. B)
