Vroman was a pioneering ethnographic photographer who documented Native American peoples and landscapes of the American Southwest in the same era as Curtis, producing monochrome images that balanced pastoral dignity with documentary integrity.

Gilpin devoted decades to photographing the Navajo people and the dramatic desert landscapes of the Southwest, creating luminous monochrome works that share Curtis's ethnographic sensitivity and reverence for the land and its inhabitants.

O'Sullivan produced sweeping monochrome documentary photographs of the American West during government survey expeditions, capturing desert terrain and indigenous peoples with the same austere compositional clarity and ethnographic purpose seen in this Curtis photogravure.
