I was playing with my fisheye lens looking all over the place, trying to find something to photograph. I went right, left, down, around and then finally I looked up and noticed something. On a day where its especially cloudy, and the skies are blue, when you look through a fisheye the sky looks exactly like Earth. I laid on the ground and stared at the sky holding the lens to my eye watching the clouds move, pretending I was gawking at it through outer space. Today, I was an astronaut.
