In this project it was hard to find people who were OK with me taking pictures of them. Someone who may look scary while not smiling could look very nice and friendly when they are smiling. If I were a photographer I would know not to let bias stop me from taking peoples photos. I would get to know them and be friendly with them instead of just asking for something right away.
