Why is the moon in photography much bigger than what the naked eye sees?

The main problem is the focal length of the lens. When the distance between the camera and the subject cannot be changed, using telephoto will bring the subject closer.

Or you can shoot a large scene with a wide angle, and if you can accommodate more content, you can shoot close-ups or partially enlarged items with a telephoto. Generally, sports reporters can take close-ups of athletes with a telephoto lens of 600mm, but there are fewer group photos taken with a wide angle, which is the reason.

Characteristics of the moon

The average brightness of the moon is 1/465000 of the brightness of the sun, and the brightness varies from 1/630000 to 1/375000. At the full moon, the average brightness is-12.7 (see). It gives the earth an average illumination of 0. 22 lux, equivalent to the illuminance of 100 watt electric lamp at a distance of 2 1 meter.

The surface of the moon is not a good reflector, and its average albedo is only 9%, and the other 9 1% is absorbed by the moon. The albedo of Guangdong Sea is even lower, about 7%. The albedo of the lunar highlands and craters is 17%, and it seems that the mountains are brighter than the moon sea.
