Video is so different from photography (no matter how fabulous the photographer), it's capturing everything that happens between the clicks of the camera. Once you experience that, then you'll see why it's so important to have both mediums.

Here's part of the first look moment from Sarah and Anthony's wedding in a great shot (among many others) from www.jason-gina.com
