A woman in Qingdao, China, practices tai chi by the Yellow Sea in 1981. It's one of the many photographs featured in Hiroji Kubota's new retrospective photo book.
Kubota has traveled all over the world during a career spanning more than five decades. This image was shot in Utah's Salt Flats in 1989.
Vietnamese refugees look at the camera in 1975. "You have to be sensitive to subjects you are photographing, particularly when you photograph people," Kubota said. "The moment you photograph, that is a very aggressive kind of behavior. It's contradictory: You have to be sensitive, yet you have to be aggressive."
