The ray of light peeking through the crack creates a blinding effect on the subject. The light is so bright that it blinds her vision, covering her eyes in the photo. The black and white filter makes the ray of light even more bright.
I really like this photo as it is not just disguising the person themselve but it is also disguising emotion that the girl is feeling. It almost gives the impression of an explosion of feeling and emotion. It can also present the feeling of insanity.
This shot communicates a lot of emotion through a melancholy colour scheme and a high key lighting technique showing a model with a somber facial expression. The use of a long exposure and a flash creates the illusion of multiple faces.
