Earthrise
Here's my deal: I don't take photos. I make them. My main tools are Terragen, Celestia, and Photoshop. Consider what I post here and in future posts an artist's conception...

It's a beautiful image, but I wonder if it's accurate. If the Earth is that close to the horizon, shouldn't the terminator (the line between light and dark) be horizontal rather than vertical? For example:

ToSeek,
It depends on where your viewpoint is located. The Apollo photograph that you show was taken from orbit near the Lunar equator, where the sun would be almost overhead. For the Earth to be near the horizon, you need to be near an edge of the visible portion of the Moon. For the Earth's terminator to be vertical, you'd need to be viewing from near a Lunar pole. Since the Earth's north pole is up in the picture, the viewpoint is near the Moon's north pole. Here's what it'd look like from further away from the Moon's surface, and if the Moon had longitude and latitude lines on it  Drawn by Celestia using Grant Hutchison's grid lines:  My quibbles would be that the shadows should be darker and the surface coloration more monotone.

Ah, good point. I was trying to think of a scenario where it would work, and I couldn't. But you're right, if one were at a pole, it would look like that.

Ironically, the Earth I used for this image happens to come from Celestia...

Cool picture, Machindo. I know the wonders that can be done with Terragen as I'm familiar with Kees Veenenbos's site; he does very cool Mars renders.
Hey, space art is fun.
