Reducing the Image Noise (Noise Reduction)

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

•when shooting with a high sensitivity setting

•when shooting with long exposures

•when the temperature of the CMOS sensor is high

You can reduce image noise by using Noise Reduction.
