The catch light seems to show us a big window with people standing in front of it. But wouldn't window light produce a more flat lighting? There is a clearly visible value change from the ear on the left side to the dimly exposed light below her eye camera-right. Do they just use the window light to create an interesting eye-light and then light the face separately from some angle that is not seen in the eyes? Or do they use some modifier to feather-off the light on the camera-right side, creating that light fall-off look that adds beautiful depth to the image?
