You have no idea how excited I was when this worked; I literally bounced for about a minute after I closed the shutter. A bus went by, nice and slow, partway through the photo, which is what gave it what height there is, along with the fact that the camera is about a foot off the ground, on a street corner.
35 second exposure at F22 just after the lights changed on El Camino and Castro. I tried to hold still, but as you can tell, trying to lock your face is actually fairly difficult, and I failed mostly.
But I really, really liked the shot.
Bit of sharpening, noise removal, and some contrast.
