You can find some of my "At night" blogposts down below.
I went to Copenhagen in early November and spent a night out in the streets for some long exposure. Unfortunately, it was quite foggy that night. I shot the Magasin du Nord, the new Opera House and the beautiful Børsen from the 17th century.
Was in Prague early October 2015 for the second time. Spend some time for long exposure in the evening and the next morning for sunrise. Was surprised with some really great colours in the morning. Blue hour went red and I really liked it. Even saw a Chinese couple doing some wedding shots in the famous Charles bridge.
