The Magna Database: Figure 1
Figure 1: A change in pose angle (when the subject tilts his head back) results in an alteration of the distances measured between facial features. The position of the exocanthion (outer corner of the eye) is held fixed in these views, and the arrows indicate the distances from this line. The rotation of the head in the right image foreshortens the distances in the plane of the face. In contrast, the distance to the subaurale (bottom of the earlobes) has increased.
