Comments
Out of hand, I take 3-5 photos, bring them in as layers in Affinity (or Photoshop), align them and merge them as median or mean for a noise-free photo.
This always allowed me to shoot at a very high ISO number. Of course, a 100mp photo requires pixel shift in the camera.
Mean-averages pixel content across the stack of images. Good for long exposure simulation and noise reduction.
Median-removes pixel content that is not consistent in each image. Suitable for object removal and noise reduction.
