The Noise Reduction Tool has been re-engineered for improved image quality. You will see better noise reduction, better retention of details, colors, and patterns, and even a more significant impact of the Amount slider.
The Noise Reduction tool has become more intelligent. The default setting will provide noise reduction results based on your ISO setting. Owing to this, Capture One 20 will provide satisfactory results even without tweaking noise reduction.
