I walked around the school and asked people to smile and not smile. The only difficulty I had was finding unique or different people to take pictures of. The changes I saw in the person was they looked more happy and less tight when they smile. Bias could affect someones job as a photographer because if someone looks mean or unhappy you would probably not want to take a picture of them. The questions I would ask are what they like to do or if they have any siblings.
