Photographs and Moving Images

Photography Collection

History Colorado's photography collection contains over 1 million images documenting the history of Colorado and the American West from the 1840s to the present day. The collection ranges from early daguerreotypes and glass plate negatives to digital prints and from Kodak snapshots to masterworks of photographic art.

The photographs show the growth and development of Colorado and her people, industries, agriculture, and communities. Highlights of the collection include the largest collection of American landscape photographer William Henry Jackson's work west of the Mississippi River; 110 years of photography from the Aultman Studio of Trinidad, the longest-operating photography studio in the state of Colorado; and the photographic archives of the Denver & Rio Grande Railroad.

A selection of photographs from History Colorado's collection have been digitized and are available to view online. Click here to view the History Colorado Online Collection, which contains images and records of photographs, artifacts, and archives.
