Yes, this is an unusual crop ratio. No, it wasn't intended for Instagram. It was because I was in too much of a rush (hence the excessive ISO that I mentioned in the previous shot), and was also too fixated on the terraces in the background (which made me think "Ah, how Parisian!")... and that made me fail to notice the overflowing green garbage bins (like the ones across the road) that I had in my foreground.

C'est la crop.
