What was wired in

Works

The dolly move and the boats are kept and the windows and lamps light up. The reflections in the water follow the new lights.

A realistic nighttime version of the same canal-side street with the same sideways camera movement: warm light glowing from the windows of the brick houses, street lamps reflected in the canal and a dark blue night sky. The two walkers follow the same path. Only the lighting changes from day to night; identical composition, framing, camera movement and motion.
