Just wanted to share a little trick... obviously there isn't much very special about this image:




Except for the fact that it was taken SOC at ISO 25600 from a M43 sensor equipped camera!


Actually, it was taken 16 times... then stacked mean in Affinity Photo. The mean stacking algorithm averages the pixels from shot to shot, meaning (no pun intended) that pixels that are in different places from image to image are subtracted from the mix. Since noise never really appears in the exact same place twice, most of it is averaged out, without the smearing/softening that traditional noise reduction causes.


So if your subject is stationary, don't be afraid to crank up that ISO and get the shot (I mean shots).
