Is there anything left to do at these iconic locations that hasn't been done before? Well, until you've been there yourself and shot it your way, yes! I love night photography. I have so much more control over what I want to emphasize. Morant's Curve isn't the darkest spot - in fact there's a lot of light pollution from Lake Louise and the Trans-Canada Highway not far away that lights up the clouds. But along the Bow River, down among the trees, it's still pretty darn dark - until a train comes. For a few seconds every couple of hours, the riverside is flooded in light as a the headlights sweep left across the dark pines, then down the river, then swing back to the right, reflecting off the snow and revealing the track and surrounding wilderness ahead to the engineer.
Interestingly composed shots that grab the viewers eye right from the thumbnail. Check out the main group on flickr: http://www.flickr.com/groups/1715297@N25
An ongoing and growing collection of photos that IMHO reveal the awesome, but seldom seen beauty of the railroad world because most of us don't get out after sundown. From dusk to dawn, lights are on! (And I continue to find new "Lights In The Night"!)
