What's the difference between seven sides and three sides of photography?

1, a seven-faced portrait, means that the subject's face turns slightly to one side, but most of the front of the subject's face can still be seen from the camera direction. If divided according to the proportion of the front and side of the subject's face, the seven-face image should be dominated by the front and only a small part by the side.

2. Three-sided portrait means that the shooting angle of the subject is more inclined to the side than that of the seven-sided portrait. Although the front of the subject's face can still be seen from the direction of the camera, the proportion of the front is not as large as that of the side. Compared with the seven-sided portrait, in the three-sided portrait, the outline of the narrower side is more vivid and important; Moreover, the height of the bridge of the nose is more obvious, and the wider contour lines on the face side are less prominent visually.
