I am a photographer.

Is there this position in your class? Very good!

First of all, you should explain to the teacher your love and familiarity with photography. Then explain to him the advantages of doing so: you can record some short films through photography and bring knowledge or feelings to yourself or your classmates; The life of the class group is also some records and beautiful memories. Of course, loving photography does not mean that you can hinder others. You should not only assure the teacher that it will not affect your classmates, but also do it. The most important point. Don't let your interest interfere with your study. After all, students still focus on learning. While considering your requirements, the teacher is most worried about whether it will affect your study.

Hey hey, this is my opinion. Wish you success!
