The Aurora Borealis shines across the night sky as the stars swirl above Glacier National Park, Montana.<br />
<br />
Photography Tip:  This photo is a single twenty-five minute exposure.  When I shot it, the Northern Lights were just a faint band of color across the sky.  If the Aurora had been bright and active at this point in the evening then this long-exposure image would have blown out and failed.<br />
<br />
The message that I hope to share today is that even a tiny faint light source will slowly become brighter and brighter to the camera if you extend the shutter speed into the seconds, minutes, and hours range.<br />
