What are the different noise types?

Gaussian noise adds a natural-looking grain similar to high-ISO camera noise. Uniform noise adds evenly distributed random variations.
Impulse noise (salt and pepper) adds random black and white pixels. Laplacian and Poisson noise produce different statistical distributions useful for artistic effects.
Random noise combines various noise characteristics for a more organic look.

What is the intensity setting?

The intensity (attenuate) value controls how strong the noise effect is. A value of 1.0 is the standard amount. Lower values produce subtler noise, while higher values create more dramatic grain.
Start with 1.0 and adjust up or down to find the right look for your image.
