Figure 2. Decrease in contrast with age.
L* contrast of the eyebrows (left) and a* contrast of the mouth (right) as a function of age of the face. Each point represents a particular face.
Table 1.
The relationship between age and luminance (L*) or color (a*, b*) contrast.

Figure 3.
Contrast manipulated versions of a face.
The left image shows a face with facial contrast increased and the right image shows the same face with facial contrast decreased.
Figure 4.
Results of forced-choice contrast manipulation experiment.
The percentage of trials for which the high contrast face was judged younger is shown in the dark bars and the percentage of trials for which the low contrast face was judged younger is shown in the light bars. Results are shown for three age classes.
