Joe’s Saturation Noise can be used to add grain and adjust the saturation of an image in one step. The effect uses a simple saturation adjustment on random noise pixels, creating subtle grain modified from existing pixel colors. The saturation controls are the same as used in Joe’s Simple Saturation.
This filter uses the same efficient noise engine as the other Joe’s Noise filters for faster rendering and smoother results.

Out of Range Colors
The Saturation controls in Joe’s Saturation Noise can produce colors well outside of the broadcast safe gamut. At high Saturation values, the entire image will likely be illegal. If you’re end product is going to broadcast, stay away from the high-end of the Saturation input and check your output levels.
The Controls
-
Source, Saturation
-
Basic Saturation controls, see Joe’s Simple Saturation for explanations of these controls.
-
Scale Noise (100 - 1000%)
-
Increases the size of the noise particles.
-
Soft Noise (0 - 10)
-
Blurs the noise before compositing it back into the image. A slight blur can prevent noise particles from shimmering on a video monitor.
-
Fixed Noise
-
Determines whether the noise changes on every frame or stays fixed for the duration of the effect.
-
Opacity
-
Sets the intensity of the adjusted noise pixels.
