Noise Reduction

When shooting with a digital camera, image noise (image roughness or unevenness) becomes noticeable in the following situations.

-Shooting with a long exposure

-Shooting with a high sensitivity setting

-When the temperature of the CMOS sensor is high

You can reduce image noise by using Noise Reduction. However, images shot with Noise Reduction will take longer to save.

Slow Shutter Speed NR Reduces noise during long exposures.

Select [On] or [Off] in [13. Slow Shutter Speed NR] of the [ACustom Setting 2] menu (p.81).

The camera determines the conditions such as the shutter speed, 1 On sensitivity, and internal temperature, and automatically reduces

noise as necessary.

2Off Reduces noise only when the shutter remains open for more than 30 seconds.

*When the exposure time is longer than 30 seconds, the maximum sensitivity is set to ISO 3200 and Noise Reduction is automatically activated.

High-ISO NR

Reduces noise at high sensitivity (ISO) settings.

Select [Medium], [Low], [High] or [Off] in [14. High-ISO NR] of the [ACustom Setting 2] menu (p.81). You can change the sensitivity from when Noise Reduction is activated in [15. High-ISO NR Start Level] of the [ACustom Setting 3] menu (p.82).
