Blue hues over Bucharest

Momentariness. The time is 17:15. Fog is slowly draping the part of Bucharest I'm in in peculiar blue hues. Photography relies mostly on light and light is fading out so I pick up my camera, climb down 3 flights of stairs in what seemed to be 10 seconds and get in the street. Picture after picture I witness the rapidly changing scenery in front of me: the initial blue tones turned in only 15 minutes to something that looks like the interior of a freezer. In the end it got so dark that not even a high ISO value won't cut it. My job there was done.
