It's hard to go wrong when you've got a beautiful South Dakota winter prairie morning with a coat of frost over everything. When you are also in the neighborhood of the Cathedral on the Prairie in Hoven things have really gone right.
Here's an accidental technique I stumbled across inside the cathedral. About two-thirds of the way through a 15-second exposure I decided to pick up my tripod and move without realizing the shutter was still open. The results are pretty interesting, so I may have to try this kind of thing again somewhere.
