For this project we had to take pictures of people and ask them to smile. It was difficult to find people to take pictures of. When the person had a natural face, they typically looked either mean or somewhat happy. But when they smiled, they were a totally different person. Bias could affect your job as a photographer because if someone looks mean or un welcoming, you might not want to take pictures of them. I would ask them about themselves and their background to get to know them more.
