Gaussian blur feature gives you a noise reduction feature to smoothen your editing experience. If you take a photo in low light, and the resulting image has a lot of noise, Gaussian blur can mute that noise. Named after mathematician Carl Friedrich Gauss (rhymes with “grouse”), Gaussian (“ gow -see-an”) blur is the application of a mathematical function to an image in order to blur it.
