I really like these photographs from Eastern Congo by Richard Mosse. There’s something other-worldly about them. They are not photoshopped. Mosse used Aerochrome Kodak Infrared film, an obsolete technology, to create the effect of purpleness.
The film, designed in connection with the United States military during the Cold War, reveals a spectrum of light beyond what the human eye can perceive. According to The New Yorker, Mosse aims “to shock the viewer with this surprising bubblegum palette, and provoke questions about how we tend to see, and don’t see, this conflict.”
