He, like other photographers of the time, depicted a romantic view of their subjects, staging shots to reflect their personal viewpoints and, in doing so, alter details and create inaccurate images. In Moorhouse's case, there are significant differences between two broad categories of his work with native people. His studio portraits of tribal members, which during his lifetime were considered his best work, are stiffly posed and probably inauthentic.
Photographers during that era frequently portrayed their subjects romantically by arranging shots to reflect personal perspectives, thus modifying details and producing images that weren't entirely accurate. Moorhouse's photographs of Native Americans illustrate this approach; his studio portraits, which were once considered his best work, are stiffly posed and likely not entirely authentic.
