The exposure was shot auto and then corrected in post which wasn't easy. There is some motion in the tripod - I think got warmer or I touched it a bit. I corrected the motion in post. I have blended the images to make this a 45fps video and to try and remove some of the residual brightness flickering.

519 frames, starting at 6:28am and running to 7:54. Sunrise was at 7:34am. The interval was 10 seconds - it started at f9, 8 seconds and ended at f22, 0.3 of a second. I didn't get the time down fast enough so some of the frames were at f22 but wanted to be more closed.

You can see some flickers at the start on the right hand side. That is flare from cars on the bridge. There is quite a bit of shaking when buses go over the expansion joints in the bridge - surprisingly that didn't show up.
