Film Grain (Studio Version Only)
Composites a procedurally generated layer of simulated “film grain” over the image. Individual simulated grains with falloff are generated to match the resolution of the project.
Main Controls
These controls let you quickly choose and apply a film grain effect.
— Film Grain Presets: This pop-up lets you quickly choose from among different 8mm, 16mm, and 35mm film grain effects.
— Composite Type: Lets you choose a composite mode with which to combine the image with the grain simulated by this plugin.
— Opacity: Lets you fade the Film Grain effect against the original image.
— Grain Only: This checkbox lets you see just the grain layer that you’re creating, so you can evaluate its look prior to it being composited into the image.
Grain Params
The Grain Params group lets you adjust the quality of the grain.
— Texture: Larger values create more separation between the grains generated by this plugin, while smaller values bunch them up closer together to create denser grain patterns.
— Grain Size: Larger values zoom into the individual simulated grains generated by this plugin, while smaller values zoom out.
— Grain Aspect Ratio: Lets you adjust the aspect ratio of the grains.
— Grain Strength: Adjusts the contrast of the simulated grain layer. Higher values produce more contrast, lower values less.
— Offset: Lightens or darkens the entire simulated grain layer. The practical effect is that lower values emphasize lighter grains, while higher values emphasize darker grains.
— Symmetry: An asymmetrical contrast adjustment. Lower values darken the lighter grains, while higher values brighten the darker grains.
— Softness: Lets you blur the grain layer to create even softer transitions from one grain to another.
— Saturation: Lets you make the grain more or less colorful. At a value of 0, grain is monochrome.
Advanced Controls
In the Advanced Controls, the Red, Green, and Blue sliders control the color of the grain. The Shadow, Midtone, and Highlight Gain controls let you adjust the amount of grain that’s composited into each of these tonal regions of the image. When the Optimized Mode checkbox is turned on (the default), performance should improve substantially. Turning on the Animate on Every Refresh checkbox will animate the grain as you adjust the sliders, allowing you a better idea of how the grain pattern will look in motion.
