A fast, effective noise reduction technique for milky way and night sky photos.
Noise can be a problem in night sky photos, as I’m sure you already know. Getting rid of it effectively, that’s also often a problem. You see, it’s difficult for algorithms in noise reduction software to differentiate between image noise and actual stars, often resulting in blurry looking stars. Thankfully, there’s a simple way to avoid this issue as photographer, Dave Morrow demonstrates in the video above.
With the help of a fresh layer and luminosity channels you can select out the darker parts of your image. From there you are just a few clicks away from a noise reduction algorithm that actually leaves your stars as they should be while removing noise from the dark areas of your image.
