Noise Reduction
The common way to get fast shutter speed in dark environment, when the aperture reaches its limit, is using high ISO value. But the high sensitivity brings more noise than low. The noise reduction function is designed for this.
Enter the function:
Click button 'Enhancement' and select 'Noise reduction'.
The interface and the description:
Amout of Noise
Set the level from 1 to 10. A higher number means clear more.
Reduce color spots:
The color spots are another kind of noise in color channel, which is caused by JPEG compression or high ISO value. Check this to reduce it. The size of spots can be set.
