(as far as I understand, dark frames are to reduce fixed pattern noise, bias frames can reduce read noise, layering of multiple light frames aims to reduce random shot noise.) | |

| Jan 23, 2017 at 14:37 | comment | added | RyanFromGDSE | Hey Smow, I don't generally shoot astro and not sure about the dark frames, frame bias, or anything about Deep Sky Stacker. From what I gather Deep Sky Stacker is a stand-alone app. Now you want to be able to do noise reduction in Photoshop? Would that be correct? If so I can make a tutorial that may help you. But before I take time to do that (I'd have to also shoot some noisy shots to use) could you let me know exactly what you're going to be looking for. | |
