Shooting in low-light conditions with a high ISO

6If you’re shooting handheld and don’t have a tripod, you may be forced to shoot at a high ISO. On dull days in dark streets it can be common to shoot at ISO 1600 or more. For a subject like portraiture this isn’t ideal, but it’s preferable to get the shot with noise rather than no shot at all. Sometimes it’s worth cranking up the ISO.
