## Long Exposure NR

When you set the shutter speed to 1/3 second or longer (Long exposure shooting), noise reduction is turned on for the same duration that the shutter is open. This is to reduce the grainy noise typical in a long exposure.

1. MENU 4 [Long Exposure NR] desired mode

| On | Activates noise reduction for the same duration that the shutter is open. When noise reduction is in progress, a message appears and you cannot take another picture. Select this to prioritize the image quality.
| Off | Does not use [Long Exposure NR]. Select this to prioritize the timing of shooting.
