Jagoda, don't worry, I wasn't alone out there. :) We had been to a beautiful Christmas concert in the Uspenski Cathedral, which ended about one hour before midnight. On our way back home we noticed the intriguing fog, so I had no other choice than going back home and grab my camera - despite the spooky hour of the day. Although this area of Helsinki is relatively safe, I was happy to have someone there keeping an eye on the surroundings while I was taking pictures.
