Publicity and Souvenir Photographs
In order to publicize performances artists distribute photographs through various media sources, such as newspapers. Artists also produce photographs to sell or distribute as souvenirs. Both of these practices date back to the earliest formats of photography, such as daguerreotypes, cartes de visite, and cabinet card photographs
Clues about staging, costuming, and how acts advertised themselves can be gleaned from these sources. However, it's important to remember that they are not documentary in purpose and aren't necessarily faithful to the production. Staging might be tweaked for a better photograph - in fact, until the late 19th century actors would generally pose using photography studio backdrops rather than on stage.
More information and examples of theatrical photography can be found on Photography and The American Stage, a project run by David Shields at the University of South Carolina.
