Here's a like to our blog post for Day 6:
I took this shot of Skógafoss with a 70-200mm lens, a circular polarizer, and a neutral density filter. I needed a longish shutter speed to blue the surface of the water in bright conditions, so that the rainbow would stand out against a smooth background. The neutral density filter helped with that - and the polarizer allowed me to increase the shutter speed even more, while also helping to bring out the brilliant colors in the rainbow. With both filters, I could reduce the shutter speed to .6 seconds at f/11. Just enough to smooth the water to my liking.
This was such a beautiful location - but the climb was steep. After my little run-in with the icebergs the day before, I couldn't climb the hill... so I stayed behind. At first I planned to just sit back and enjoy the beautiful sunshine while I waited, but the more I looked at the falls, the more I wanted to shoot it. The view from below wasn't very exciting... I wanted something a little different. And this is the result. This was the best weather of the entire trip, too. Warm and sunny! Such pleasure after yesterdays difficulties!
