What do you mean by a bust?

This kind of photo refers to the photo taken by the photographer from the chest to the top of the head.

Half-length photo refers to the photo taken by the photographer from the chest to the top of the head, which can make the subject occupy most of the position of the photo and reserve a part of space to explain the background of the character.

Half-length photos can be divided into half-length photos and upper-body photos. Half-length photos generally include the part above the legs of the characters, and upper-body photos include the part above the waist of the characters.
