Montreal-based Canadian photographer Christopher Forsyth has been capturing the abstract beauty of his city’s underground system in a series of stunning images titled “Metro Exploration”. He has been sharing the process on Instagram over time using the hashtag #mtlmetroproject. Since the Quebec provincial law prohibits photographing strangers in public places, Forsyth has gone to great lengths to shoot in deserted stations. You can view more of the project and purchase prints at his website.
