Thank you. I went for a week, the other week, and it rained every day. I didn't see a sunrise and only saw one partial sunset. As you the northern lights: nothing.
But as it was my first trip to Iceland, I can't wait to get back there.
As for ML, virtually every image started with an ETTR exposure and many were dual-ISO.
It is really impressive to compare a dual-ISO + ETTR with the final list processed image, so I'll likely post a few examples on my big soon: photography.grayheron.net
