Hi there,

all scanners produce some level of noise on dark areas, all of them to different levels but it is always present.

For that we have created Multi-Exposure which will not only help reduce image noise produced on the dark areas, but also increase the dynamic range.

You might want to activate Multi-Exposure for this kind of pictures

Kind regards
