When applying noise reduction, SILKYPIX provides four adjustment parameters: Color Distortion, Fringe Reduction, Neat Noise and Smoothness. These apply noise reduction algorithms to both bright and dark areas of your photo.
Level of shadow noise reduction allows you to adjust only the noise in dark areas, but based on the four parameters. Especially in the case of increasing Smoothness, it is possible to lose desired detail. Increasing the level of shadow noise reduction can restore details.
