Cool Desktop: Spectrum of a Tree

My wife has been using this image as a desktop background for about a year now, but recently I took a good look at it.

Initially I thought this was simply a photo of a tree in silhouette, sliced, colourized and laid out as you see it.

But on closer inspection, it seems that these are shots of the tree, at various times and seasons, with different coloured sky in the background. The website doesn’t really have detail on how the image was created.

The photographer also created Spectrum of the Sky — but I like the Tree better.

Atlantis on the Sun – Desktop Image

I felt the need for a new desktop image for my computers, now that the Apollo 11 excitement has died down, and I was tiring of my Apollo 8 Earthrise image.

I found this neat shot of Atlantis transiting the Sun, by Thierry Legault. The following sizes at the NASA site:

And my crops adjusted to fit my desktop sizes:
1280×1024 (crop)
1680×1050 (crop)
