Add Noise

All digital images have a certain level of noise (random pixel distribution) which helps to create atmosphere, texture, and depth. After image manipulation, such as resizing, cloning, applying gradients, etc., this texture noise is often lost and the image can take on a very flat appearance. The Add Noise filter adds random pixels to the image, introducing a level of noise to help return the textures in the image. This also helps to seamlessly blend effects.
