When he got to South Africa, Mark found a school and knew what he wanted to do. "When I told the teacher that I wanted to take class photos, the kids were amazed," he says. "They giggled. They laughed. They all cheered and screamed. They had never seen a camera in their life. Their expressions were priceless. Seeing the reactions was the most joyful experience. I see inspiration. I see that there can be change in this world. I see hope. My plan now is to go back and deliver these photos. For me, this is just the beginning."
