Noise Reduction

Noise Reduction treats luminance and chroma noise separately. It is a global recipe and is off until enabled.

Controls

• Luminance smooths grain-like brightness variation. High values can remove real texture.
• Chroma smooths colored blotches. It can usually be set higher because real color changes more slowly than fine brightness detail.
• Auto analyzes the frame and proposes a balance.

Inspect at 100%. Increase Chroma until colored speckling is controlled, then add only enough Luminance to make brightness noise acceptable. If texture becomes waxy, reduce Luminance.

Detail's Smoothing control moves both kinds together. Setting Luminance and Chroma to the same value is equivalent to that simple treatment; the value of this section is independent control. Avoid using both heavily, because the photograph would be smoothed twice.
