A horizontal sepia-toned photograph from the late nineteenth century captures a large river steamboat moving across a wide, calm body of water. The steamboat is positioned in the center of the frame, facing toward the left, with a dark plume of smoke trailing from a single tall smokestack. The vessel features multiple decks with rows of small windows and a prominent paddle wheel housing on its side. Several small figures are visible standing on the upper decks. In the background, a flat, dark shoreline stretches across the horizon under a pale, hazy sky. The water in the foreground is light-colored and reflects the sky, with subtle ripples following the boat. Below the photograph, a horizontal color calibration target featuring various colored squares and a grayscale step wedge is visible, included for archival digitization.
