Experiment: Night Photos of Snow

Starting Saturday evening we had about 18 hours of steady snow that left us with about 6 inches in the yard and some respectible low temperatures (like 3 degrees). I wanted to take some snow pictures and decided to do some experimenting with my 50mm lens and new tripod. All of these pictures were taken in natural light at about 11pm with very long exposures and an ISO speed of 100. You can tell it is night by how brightly any artificial lumination source glows. In the third photo taken from the loft, you can see the lights from the high school off in the distance. One cool thing is with the long exposures (about 6 seconds) you don't see the falling snow. All of the color is "natural" (no photoshop). Since most of the outside lighting is sodium vapor with a single wavelength, you end up with a mostly black and white sepia-tone affect.
