Noise Generator

Noise Generator is an Adobe Photoshop plugin suite that can produce various types of random noise.

Three of the Noise Generator plugins add some noise to the original image, little noise, medium noise, or strong noise. The strong noise plugin modifies every pixel in the image, the other two skip a certain number of pixels. The effects of the plugins are cumulative: Run them repeatedly to add more noise.

The Color Noise plugin fills the image (or selected area) with random RGB pixels. The effect is not cumulative, rather it is different every time, completely random. Because of that, if you use it on different frames of an animation, the noise will be changing.

The White Noise plugin works just like the Color Noise plugin, except the noise will be monochrome (shades of gray).

The Alpha Noise plugin fills the alpha channel with white noise, thus adding random transparency to each pixel.
