If you have ever wondered how other photographers are able to shoot in pitch-black conditions, you are not alone. Many photographers don’t take out their cameras in those situations. The answer, however, is simple: Just raise the ISO (Figure 7.1). Adjusting the ISO on the fly is easy; simply press the ISO button on the top of the camera and use the Main dial to adjust. In typical shooting situations, you should keep the ISO in the 100–800 range to keep your images free from noise. But as available light begins to disappear, you might find yourself working in situations where you will need to use the higher ranges of the ISO scale.
