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.
Pictures cannot be taken while the camera is performing a noise reduction
process. In particular, if you use [Slow Shutter Speed NR], it may take more
time to process.
