The vertical banding on the first shot was quite noticeable but in this more recently posted shot it is only just noticeable but the noise is more so. Go figure. I notice vertical banding on some of my own shots when I underexpose by a stop or more and there are solid dark areas in the shot. I agree with Tom that this ruin some shots - the lesson seems to be don't underexpose dark subjects.
