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.
Happiness has no age! I like this photograph due to how natural the model is in the image and how the photographer has made a strong connection here in order to make the woman laugh. I also love the woman's eyes and how they tell her story as a person.
