Hi Bob! I remember parking in front of that Target. I also took note of the starbursts in your images posted earlier. When you look through the lens and the aperture is wide open, can you see anything of the aperture blades? Or anything that appears to change size as the lens is zoomed? It's a remote possibility but with the Canon 16-35/2.8, I noticed it has a second aperture that changes size as the lens is zoomed, which is visible from the back of the lens. I assume it's to keep the aperture value consistent throughout the zoom range.

Ron, using a flashlight, I can see the shape the aperture blades form . . . sort of an octagonal (stop sign) shape. Looking through the back (hard to see) or with zooming, I don't see anything to suggest a second aperture. Zooming just shows the internals of the lens changing but not to the aperture blades. In the end, I like the look anyway!
So, here's a tripod mounted long exposure shot. Next time some with legacy lenses like my Minolta MD 35-70/3.5
I had the pleasure of meeting Michiel, who turned out, unsurprisingly, to be a real charmer of a man, and his 2 shots with a lens he didn't know show what a cracking photographer he is. Michiel, it was too brief, and my fault, too! I will do that again, any time and any place, in a heartbeat!
First shot with Leica R 28mm Elmarit vII, second with Loxia 50mm. Both, like Michiel's, of the Gehry-designed Louis Vuitton Foundation
It was nice to meet you but you flatter me Philippe. We will meet again some time!
Here is one from the inside; one of the installations by Olafur Eliassen. ISO 1000
