Chapter 6 Noise reduction This function reduces the noise that appears on images during long exposures. When shooting night scenes, shutter speeds become slower and noise tends to appear on images. When noise reduction is set to ON, the camera automatically reduces noise to produce clearer images. However, shooting time is approximately twice as long as usual. Noise reduction can only be used when the shutter speed is set slower than 1 sec. Noise reduction: OFF Noise reduction: ON ● The images here are only for showing noise reduction effects.

During this time, shooting the next picture is not possible. ● When NOISE REDUCTION is ON, sequential shooting ( , , BKT) is not possible. ● This function may not work well with some shooting conditions or subjects. ● Since the shutter speed is slower when noise reduction is ON, we recommend that you use a tripod. 116
