I've seen many pictures of the Basilica at Sacré-Cœur and it is certainly one of the most photographed structures in Paris, if not the world. What is less observed is the stony tower to the north housing one the heaviest bells on the earth.
I recall the morning this shot was taken to be particularly overcast and despite the elevation of the Basilica it was also a bit muggy. By the time I climbed the topmost dome the clouds had begun to part way to the sun and a brilliant blue sky, which I have tried to capture here against the stark white travertine of the bell tower.
I should add that with the Bronica SQ-A (which is at times an unwieldy medium format camera) and with square format in general, I tend to lean towards symmetrical compositions. 6x6 images sometimes benefit, I find, from this type of framing to accentuate both the final image itself and the medium itself.
