Today’s potd is an attempt at a long exposure. In retrospective, I should’ve stopped down to f/16 instead of f/8, and exposed eight instead of four seconds. But I think it’s okay for a first try

Leica M8 + M-Rokkor 28/2.8 @ f/8, 4 sec, ISO 160

The scene shows the buildings of the humanities of Marburg’s university to the right, the “Stadtautobahn” (the federal highway number 3, which has four high-speed lanes intersecting the city) in the center, and an electronics superstore to the left.
