Reduce image noise
Image noise is extraneous visible artifacts that degrade image quality. Image noise includes luminance (grayscale)
noise, which makes an image look grainy, and chroma (color) noise, which is usually visible as colored artifacts in
the image. Photos taken with high ISO speeds or less-sophisticated digital cameras can have noticeable noise.
Moving the Luminance slider to the right reduces grayscale noise, and moving the Color slider to the right reduces chroma noise.
