Painting with light

I took this image in the Palouse region of Washington State. It is a 30 second exposure in which I used a flashlight to paint the landscape and the barn with light. I did a couple of test shots to determine the exposure. Notice the texture on the grass; that came from the fact that I walked about 30 feet from the camera so I could sidelight the scene. This produced a much more pleasing image that I would have had from front lighting it. I got really lucky with the clouds. In the dark of night, they could hardly be seen. With the long exposure, though, all that detail was revealed. My other settings were f/2.8 and 2500 ISO, and I set the camera to daylight white balance.
