This week's Hot Pic: "" by Mike Keller, Towson, Maryland

Mike says: "I shot this in the Grand Teton National Park around 10 p.m. in pitch black. I intended to capture the Tetons at under the Milky Way, but this turned out to be more complicated than I expected--not only was it so cold that I had to wear gloves when I wasn't adjusting the camera, but I had to work under a dark blanket in the middle of the night. Luckily, my wife had a little flashlight with her, otherwise, I probably wouldn't have been able to get this image. I shot the picture with a Canon EOS D50 with a 30 sec exposure at f/4 and ISO 2500. I made a few minor adjustments with Photoshop CS4--mainly, I eliminated a little noise in the sky and altered the composition."
