This lesson plan closely examines four of the 13 million photographs in the Smithsonian. The pictures represent four important steps in the history of the medium:

• introduction of portrait photography
• invention of a photographic printing process
• capture of instantaneous action
• advent of home photography

Through the lessons, students will see that, while not every picture tells its own story, every picture has a story behind it.

These lesson plans were created by art teachers as a means to introduce students to the possibilities of photography for documenting the world around them, and as a mode of self-expression.
