First off...great image. Just the fact that you were there to see that.

As for the noise:
  1. I am not sure what you think, but even your out of camera image with the R6 at ISO 6400 looks very good to me.
  2. Especially pixel peeping, DXO PureRAW pretty much cleaned up most of the noise. Not ISO 100 clean...but that is like ISO ~800-1600 clean, so ~2-3 stop improvement?


What do you think?
