Final answer:
Lewis Hine's photographs were intended to bring attention to and advocate for child labor reforms by documenting the harsh conditions faced by child workers.
Step-by-step explanation:
Photographs taken by Lewis Hine were primarily intended to focus attention on the need for child labor reforms. As a photographer for the National Child Labor Committee (NCLC), Hine embarked on a decade-long photographic campaign to educate Americans on the harsh realities of child labor.
His images of young workers, such as Addie Card, a twelve-year-old spinner in a mill in Vermont, and young boys working at Bibb Mill in Georgia, showcased children operating large machinery, which was dangerous and often resulted in injuries. These photographs not only highlighted the exploitation and hazards these children faced but also played an instrumental role in advocating for legislative changes.
