Moon image here looks kind of odd...
It is a real image of the moon, imaged by me years ago, showing a half Moon with the Earth shine.
(Shadowed side of the Moon get lit by the light reflected from the Earths atmosphere, hence the bluish color)
Actually you can't see the Moon from Earth from this angle! Images are done by re projecting the moon image to a sphere made by a 3D-software. After that you can select any new viewpoint to a Moon, as long as the point of interest stays on the visible side of the Moon. It's kind of having a private Moon orbiter.I like this method, since the actual image data stays practically untouched, it just get seen from an other angle.

I developed this technique back in 2005. At the time it gets published by the "Sky & Telescope" magazine.
(J-P Metsävainio, A New Way of Looking at the Moon. Sky & Telescope, Jan 2005, p 142-146.)

I have made several short movies with this technique, here are some links to them:
