When we developed our new noise reduction algorithm in the upcoming ON1 NoNoise AI photo editing software, we took a holistic approach to understand noise and its causes. Thinking like a doctor, if we could prevent noise, that would be better than just treating it. A lot of the research bears this out. The earlier you can tackle noise, the better. A lot of the image noise we see in digital photographs is a side effect of the demosaicing process. If you are unfamiliar with that term, don’t worry, I’ll explain.
