[1] Little is known of Homer Scott's early work before 1911-1912, when he made several trips from El Paso, Texas into Mexico to photograph and film both sides of the Mexican Revolution.

His war photographs were syndicated by Newspaper Enterprise Association, and he also furnished images for the New York Herald, Collier's, and Leslie's Weekly.

[6] Scott's first known cinematography work in Southern California was The Key to Yesterday for Carlyle Blackwell's Favorite Players Film Company in 1914.

Scott freelanced for several years, and in 1920 filmed noted underwater scenes in Annette Kellerman's What Women Love (1920) and Maurice Tourneur's Deep Waters (1920).

In 1923 Scott filmed Little Church Around the Corner, Main Street, and Where the North Begins[11] for Warner Brothers.
