Lawrence Denny Lindsley (March 18, 1878—January 3, 1975) was a photographer, writer, and business owner; the grandson of early Seattle settler David T. Denny. Famous for his many photos of Mount Rainier, the Lake Chelan region, Snoqualmie Pass, and other areas (and the lengthy captions he prepared for them), he extensively studied mountainous species in Washington state that were unknown by Western scientists. During his career, he worked with both Asahel and Edward Curtis, and helped to develop the orotone print process.

Jesse Tuomley Banfield (June 16, 1877—September 15, 1946) was a pictorial and landscape photographer from California. His work was exhibited throughout the United States and Europe throughout the early 20th century. In 1929, he jointly incorporated his studio in San Francisco, the Banfield-Hullinger Company, with support from fellow photographers Arthur Pillsbury, and his sister Aetheline Banfield.

Oliver Scott (O.S.) Van Olinda was a journalist and photographer who lived on Vashon Island, Washington. Born in La Salle County, Illinois, he moved from Nebraska to Vashon Island, Washington, and became involved with publishing. He typeset weekly papers, edited others, and managed wireless stations while serving as historian of the Vashon-Maury Pioneer Society over the course of his career. He wrote the first book chronicling the settler history of Vashon Island, History of Vashon-Maury Island.

James B. Barton was a photographer living and working in Seattle from approximately 1900 until the late 1960s. He is listed in the city directory variously as a bookeeper, collector, photographer, salesman and insurance agent. James B. Barton and his brother Arthur formed the Barton Brothers photography studio.

Beverly Bennet "B.B." Dobbs (1868—1937) was a non-Native photographer and filmmaker in Alaska and Washington State. He is believed to be one of the first individuals to have used motion picture film north of the Arctic Circle.

Dobbs moved to Nome, Alaska in 1900, and entered photography after achieving little success during the Nome Gold Rush (1899-1909). Dobbs photographed landscapes in the Nome area, including within the Seward Peninsula, as well as Native Alaskans in these places. His photographs of Native Alaskans garnered him national attention.

Near the end of the Nome Gold Rush, Dobbs found success using motion picture film, and soon moved to Seattle to pursue filmmaking. In 1911, he sold his photographic negative collection to the Lomen Brothers Co., who later issued some of his work under their company name.
