About three years ago Dante Vono sent around some links to photos he had taken in Italy. They were really great photos, but what hit me more was that he had taken a handful of them with an audio recording as well. I looked at those photos and listened to the audio and was amazed at how the sound just transported me to the place. Arguably, it was more powerful than just watching a video of it.
Inspired by his example, I attempted to do something similar using my Zoom H2 in Glacier National Park. Hit play to experience this picture fully. I like how you can hear the rapids in the background with the water dripping off the rock over the top.
