This series of long exposure photos taken in St. Petersburg (Russia) are incredibly creepy (and this very cool), but when I first looked at them, I thought the people were some kind of paranormal dirt cloud. I think the most unnerving parts of these photos are the hands and faces. You’ll see more of them and read more about “City of Shadows” by Alexey Titarenko and how he created these images in the article Pandemonium at BLDBLG (via).
