Rand Node

Creates uniform Random noise. This node alone is not suitable for image regrain.

2 different Rand with different values of “Density”

Usage

The “Density” parameter allows one to change the average distance between the random dots of the noise

check “Static Seed” for a freeze frame of the effect

Noise Node

Creates noiseover the source image.

2 different types of Noise. Poisson on the left, Gaussian on the right.

Usage

The Sigma parameter control the amount of noise.

The “type “Poisson” noise reacts to the source image. It could be used to simulate electronic sensor noise. It gives a black result when no source image is provided. Type “Gaussian” is more uniform and is not dependant on the source image
