ABSTRACT
Noise can also be used to reduce banding effects that are often introduced by gradients.
To illustrate this I have created a color gradient which clearly shows the lines between tones of the color gradient. Adding a small amount of noise removes these, making the gradient smoother and a little more natural. Adjust the slider and watch the image. You can always undo (Ctrl+Z) if you are not happy with the effect. I used a setting of 0.6%. Any more and the grain became too noticeable.
