When every other inch of Paris seems bathed in light, the rails exiting Gare Montparnasse make for an odd dark vein through the cityscape.
My favorite part of a huge cityscape view is the way the tiny details of buildings (windows, lights, roofs) slowly become less and less distinct as you look farther away. I was inspired to get a “real” camera all those years ago in part from a desire to takes pictures that gave the viewer a feeling of being able to “zoom forever” and always see more detail.
Even as a slightly abstract bokeh, the shape of the Eiffel Tower is so iconic as to be (nearly) unmistakable. Given the origin of the word “bokeh,” perhaps the Tokyo Tower has a better claim on being the iconic delta-shaped bokeh building.
After nightfall, the Eiffel Tower puts on an hourly strobe light show that transforms the tower into a sparkly pillar in the city skyline. Much as a flash can brighten a photograph, this effect also means that long-exposure photographs of the tower make it the brightest object in the skyline by an order of magnitude.
