Star Trails from Tunnel View, photo by Harold Davis. View this image larger.

Driving into Yosemite on a clear November evening, I stopped at Tunnel View for this 25 minute exposure from the classic Ansel Adams view spot.

With night photos, the color depends on your white balance setting (star light is not sun light). Night photography utterly baffles auto white balance settings, so the best bet is to correct the white balance in post-processing.
