Thanks, NNW. You had a couple of stunners yourself.
I was gob-smacked by the AMAZING array of ice patterns we encountered on that walk.
This is probably the first shot I'm really happy with from my RX100m2 - which is a bit too complicated for my technophobia.

It'll take a long time to get the hang of it. But with the bigger sensor I've got more options for cropping and still have a reasonable quality image. I decided that as i'm going lighter, it wasn't worth trying to replace my never-got-a-sharp-shot basic DSLR.
