When the visibility outside went from crystal clear to near zero there was no doubt about the nasty thunderstorm that was on its way. When the rain started battering the windows there was little that could stop me from putting my macro lens on my camera and start shooting the droplets on the window pane. The little dark spots that you see are tree tops in the background. Even with the lens stopped down to f/22, it was impossible for me to get a clear view of the background. And that is what prompted me to go in for this shot :). Converted to B&W using BibblePro V5.
