Basilique du Sacré-Coeur de Montmartre, Paris
t= 25 seconds exposure;
long exposure on architecture can create some very creative results. I have always admired such work, especially if used metaphorically to convey the sense of permanency (relatively speaking) contrasted with the transient movements (clouds, humans). I had the good fortune of visiting this amazing landmark of Paris on a cloudy evening, although for only about an hour.
lesson learnt – it does not matter if photography is your primary focus or not, If you are in Paris, do yourself a favor and go see the Sacre Coeur Basilica in Montmartre, and give yourself at least half a day.
