If you have been lucky enough to have witnessed the Aurora Borealis you know that it's really hard to describe the experience, either with words or photographs. Standing out in the cold night staring at a sky that is dancing in green, blue and pink is an experience that sticks with you.
A few times now, I've been lucky enough to photograph this natural phenomenon through various visits to Iceland and Canada. No matter how often or how visible it is, I never get tired of chasing the Northern Lights.
