Richard Misrach (born in Los Angeles, California in 1949) is an American photographer known for his photographs of human intervention in landscapes and for his influence in large-scale color photography. His works are represented in more than fifty major museum collections around the world.

Richard Misrach has worked over 40 years using landscapes. His best known series, Desert Cantos, is a ongoing series and a multi-faceted study of man’s relationship towards his place on earth. He has other bodies of work that include his thoughts and study of weather, time, color and light in his photographs of the Golden Gate, his records of the industrial corridor down the Mississippi River known as Cancer Alley, and an aerial viewpoint of human interface and isolation called On the Beach.In his most recent projects, they depart from his usual work. He has researched new technology in digital capture and printing. Misrach uses the negative as an end in itself and digitally creates images with astonishing detail and color. More recently, he built a powerful narrative out of images of graffiti produced in the aftermath of Hurricane Katrina, made with a 4-megapixel pocket camera.
