These photos of tunnels captured by PicsArtists are exemplary visual achievements of perspective. A lot of people might not expect something as commonplace as a tunnel to yield a great photo, but these shots beg to differ. One of the things you may notice is how perfect a tunnel is for representing perspective and depth of field. Looking down a long corridor of shrinking patterns and streaming lights is hypnotically beautiful.
