|Creator||Timothy H. O'Sullivan|
|Context||Photography had become advanced enough by the Civil War so that photographers could record still scenes after battles.|
|Audience||The general Northern public; often viewed as traveling exhibits|
|Purpose||To depict the aftermath of battles (Gettysburg and Antietam)|
Photography was invented two decades before the Civil War began, but it was still a laborious and delicate process. The bulky cameras of the day required long exposure times (five seconds) and, therefore, could not capture movement. The conflict's duration and scope, and the growth of reporting contributed to a boom in photography.
