Do you need a degree to learn photography? Is my junior high school education okay?

No need. There was once a child of 12 years old whose photography won an international prize. what do you think? This requires some professional knowledge of photography. You can teach yourself or hire a professional photographer.

I'll give you a portrait composition guide, starting with the basics.

If the position of your portrait photo is in the green line below, it is ok; If the interception is at the red line, please cut it off and practice again.
