- Fewer white blotches. If I view the largest copy you have on Flickr (2048x1366) there are fewer white spots, and the spots tend to be smaller. Still more spots than I hope to see at ISO 100.
- More natural looking. Both photos were done with auto white balance? Did you process them the same way?
Note that the exposure lengths are close but not the same. 861 seconds vs 908 seconds.
They are processed a little different and with WB adjusted in post.
I find the amount of white noise to be way, way, way, to much. I have never seen this on my K-5 or K-3.
If I use LENR it will improve dramatically. But from never having had to use LENR to must use LENR is not very fun. Hopefully the cold climate will lessen the problem.
