There are many places in the university that use ID photos. For example, photos on student ID cards, clubs, student recruitment, etc. You need to use an ID photo. In fact, you can do it yourself, you can do it at home, and you don't have to take a special photo. There are many apps that take photos of ID cards, so you can search for them yourself.
Pay attention to dress neatly when taking pictures, don't wear clothes with hats, and try to dress formally if possible. Girls should put their hair in order and show their ears. Boys should not keep too long hair, sit up straight, with their chin slightly drooping and their shoulders relaxed.
