Night or Day

I (Chris) popped out after work to get a haircut. As I left the hairdressers around 6.15pm, the darkest clouds I've seen in quite some time were coming over whilst behind me, the sun was low but still shining. I walked around to the lake to capture this photo, its clearly day time with the light on the buildings but the sky makes it look almost like night. About two minutes after this photo, the rain began to fall!
