Probably one of the most common and annoying situations for amateur photographers is that of photographs taken in dimly lit spaces late at night…And so the image noise appears. First, the photo must be "illuminated". For this, we use the adjustment bar with Fill Light slider.
To eliminate this image noise, we will use the slider adjustment bars in the Noise reduction box in the Detail panel. First, drag the Color - Color and Color Detail - Color Detail sliders to a maximum of 100 for good color retention in the image. Then the Luminance slider, which is initially at zero, we drag it to the right to a level that reduces the image noise as much as possible by combining those colored dots with the image, without losing too much of the image clarity.
After obtaining an image in which the noise is no longer so obvious, the Luminance detail slider is used to highlight the image details as much as possible. Be careful not to abuse it too much because it will bring the image noise back. Ideally, the Luminance Detail slider should have a lower level or at most equal to Luminance.
