This fantastic collection of subway photos from 1970's and 80's New York City are great to look at.

“I wanted to transform the subway from its dark, degrading, and impersonal reality into images that open up our experience again to the color, sensuality, and vitality of the individual souls that ride it each day.” In “Subway”, passengers of the city’s subterranean world are portrayed in detail, revealing the interplay of its inner landscape and outer vistas, set against a gritty, graffiti-strewn background and displayed in tones that Davidson describes as “an iridescence like that I had seen in photographs of deep-sea fish”.

This was all over Tumblr the other day. It's via them.
