Conqueror of Time.
I created the effect on the moving clouds with a 1.5+ - minute exposure. Extended exposures help create a blur effect on moving elements in the frame (water, clouds, cars, people etc...); the technique is often referred to as "time painting"; it is performed in-camera, NOT with Photoshop. Photo taken at sunset in front of Notre-Dame Basilica in Old Montréal. Summer 2012.
