Francois, Eric, Paulo, Peter, and Dave - thank you.
Pieter asked: "All these light photos have a serenity as if there is no wind... is that true?"
Definitely not true. A strong wind or gale often leads to fast-changing dramatic light but then you are forced to ditch the tripod and switch to hand-held shooting. I think all these images were composed from the tripod. In this latter event, while a gentle wind allows for tripod shooting, it can make life uncomfortable, especially for the exposed fingers (even with liner gloves on). I remember many of the sting-in-the-fingers days well. Also, what I did not mention is the low hit rate. On many of my outings, the light didn't happen and I had to return with nothing. Part of the thrill of shooting in Iceland is this unpredictability.
