From atop the Tour Montparnasse. I recall literally running through the streets of Paris with my gear trying to catch the sunset light from the building’s top floor.
I remembered a quote that made me chuckle: “Amateurs worry about equipment, Professionals worry about time, and Masters worry about light”.
Inside, they had these huge massive windows that reflected the fluorescent bulbs. So I improvised and used my jacked as a curtain, by hanging it over the camera and window. The entire setup looked really dodgy and I was getting eyeballed by people. But I got lucky because there was no security around to kick me out.
Oh how I wish I could visit Paris for some awesome time exposures!
