For some reason when I depart from my preference genre of landscape & nature, it's usually architectural work. I like the orderliness of buildings with their vertical lines and carefully thought-out ratios and patterns. This image was taken at an airport parkade. I was idling for an afternoon with my camera while on an overnight stop. At first, I was drawn to the grid pattern on the facade, then the stairwell behind, and finally the refection of a prairie sky and pedestrians walking along an overpass. After that, it was only a matter of patience and time to get the right composition as strangers filed past.
