Apocalypse, Vulcun, and Caelus were shot together because they are interacting with each other. Quirinus, Summanus, and Neptune were shot separately and dropped into the picture. I had to cut and paste Summanus' and Neptune's heads in from different shots because they can't look up like that. Blemishes and screw holes were covered up. Glowie bits are Inner and Outer layer styles. Quirinus fire breath was created from my custom smoke brush. I added a dust cloud by overlaying one of my cloud photos.
The stars are a couple of noise layers. The swirling galaxy in the background is from a NASA photo of a hurricane that I distorted. The foreground surface is a NASA photo of the moon's surface. The planets are from marble texture images I found online and Spherized. The sun is from a lens flare.
It's pretty fun and simple to create these kind of space backgrounds. Just another option until I get a chance to photograph some more sunsets.
