Instruments of Social Change

The photos should be candid if they're of people, and large enough that we can cut off the head if necessary. Typically, we like headless people, or even just hands. We are looking for people young adult to adult, not teenager or college-aged. Definitely not like Habitat for Humanity – more like something that can evoke disaster relief, goals of nonprofits, therapy sessions and other stuff "good" people do. More occupational vs. volunteering. Also, a painter creating a piece that evokes the idea of art as a catalyst for positive social change is something we really want. Any of these types of things will do, though! Pretty much bright images of people or top-view desk/table setups that evoke a desire for positive social change through work (art, social work, assistance abroad). What does a career in "Peace and Social Justice" look like? Is there a way to make forensics look inspirational?

Thanks so much!
