It was difficult because l was asking every person for 2 photos one smiling and the other one without smiling for a project. But some people was “No I don’t like take photos” And its ok if they don’t want to I can’t take photos without permission, And that can affect a photographer, And also some people got mad and others people they was very nice. The change was one photo smiling and one without smiling, And I got 30 photos of 15 people. Every time I ask a person for a photo I say may I take a photo of you please is for a project and I need one smiling and one without smiling please, Some people say of course you can.
