During my trip to Iceland, I participated in a photo tour led by Tony Prower. The tour was a five day trip along the southern coast of Iceland.
I arrived in Iceland a few days before the tour to explore Reykjavik. This ended up being a good plan as I had some of the best light of the entire trip during my first two days in Reykjavik. While in Reykjavik, I enjoyed walking the streets of the city and logged more than 40 miles of walking over a three day period. One of my favorite locations is the Harpa Concert Hall.
I visited the Harpa Concert Hall early one morning and captured photographs of the interior. It was nice having the place practically to myself. And, I never once had any issues using a tripod during my time in Iceland. I moved some chairs and tables from the open floor to clean up the frame before shooting this scene:

Here are some of the interior photographs:
