Keep the ISO Low

In previous posts, I've written about raising the ISO setting to help the camera "see in the dark." But this is not necessary if two things are present: 1) your subject is stationary and 2) your camera is stationary. When neither the camera (on a tripod) nor the subject is moving, then the exposure time can be as long as necessary to gather light.

Wise River Club, Wise River, Montana
ISO 100, 6 seconds, f/8, 24mm

In the night exposure here, I kept the ISO at 100 to prevent noise and used a six second exposure to record the outside of the building and sign.
