Photoshop Noise Reduction Sliders
There are four sliders (on right) that you need to play with to reduce some of that noise:- The strength controls the amount of luminance noise reduction.
- The preserve details slider adjusts image details like hair. A high value preserves the most image detail but doesn't reduce the noise as much. A big part of reducing noise is balancing the strength and the preserve details slider.
- The reduce color noise controls remove any random color pixels you may have.
- The sharpen details slider sharpens the image.
