Final answer:
Brianne's photographs were a successful fundraising tool for Hurricane Sandy relief because they likely elicited emotional responses, raised awareness, and encouraged donations through visual storytelling.
Step-by-step explanation:
The photographs Brianne sold at the fundraiser were a good way to raise money for the families affected by Hurricane Sandy because they likely conveyed the emotional and physical impact of the disaster, helping to raise awareness and sympathy among potential donors. Visual storytelling, such as the examples provided by Jacob Riis and the reference to the aftermath of Hurricane Charley, can be a powerful tool in humanizing the victims of such tragedies and encouraging generosity. Furthermore, the personal connection people often feel towards photographs can motivate them to support causes illustrated by these images.
