The human face is capable of infinite variety. When the expression changes, or the angle of view, the whole context of the face can change.
Lighting changes the contours of a landscape—a mountain looks very different at sunset than at sunrise. In the same way when you change the quality or direction of lighting the appearance of a face also changes.
In all its infinite variety, a photo of a face can also become a vessel for our projections about a person and what they are feeling.
For example, another photo of this model makes it seem clear that she is a down-to-earth, sensuous person. However, this portrait shows an almost religious and devotional aspect. I think of the pairing of intense devotion with carnality as the Mary Magdalene look.
Shot through a gauze curtain (it took a fair amount of post-processing to “iron” some of the wrinkles out) using a single strobe to the left and above the model. Exposure data: 200mm, 1/160 of a second at f/11 and ISO 100, hand held.
