You don't see YouTube videos like this very often, and as one commenter put it: "This video so captured the heart of this story... if it doesn't move someone, they should check their pulse."
While most on-the-ground videos covering disasters and other world events are hurried and low-quality, this one is beautiful and professional-looking; it was made by a photographer named Michael Deppisch, who used a Canon EOS 5D Mark II digital SLR camera. That model that has become extremely popular with photographers who dabble in artful online videos thanks to its excellent HD video capture mode.
If you've moved by the video, consider donating to the relief efforts by the Middle Tennessee chapters of the American Red Cross, and if you have any other ideas on how to help out with recovery from the disaster, share them in the comments.
