The Grain effect emulates the effect that real-world cameras produce where small particles in the camera’s film give the image a coarse, unprocessed effect. The Grain effect available in Unity is based on a coherent gradient noise.
|Colored||Enable the checkbox to use colored grain.|
|Intensity||Set the value of the Grain strength. Higher values show more visible grain.|
|Size||Set the value of the Grain particle size.|
|Luminance Contribution||Set the value to control the noisiness response curve. This value is based on scene luminance. Lower values mean less noise in dark areas.|
Colored will make the Grain effect run faster.
