The key light is pointing down above the model’s head – maybe it’s a household light?
The light is casting strong shadows underneath the model’s features which is not very flattering it makes the model appear fierce and manly.
This is quite a grainy image so i imagine it’s been shot on film, the light is also illuminating the smoke in front of her.
Whatever the light source was it must be quite close to her head to be causing a shadow on the wall above her head.
The lighting style makes me feel like i’ve stepped into a biker pub, It’s scary and uncomfortable, her left eye is almost completely black which is unnerving – not being able to see the model’s eyes always creates an uncomfortable situation.
The harsh shadows underneath her features creates a masculine look that makes her look intimidating, the smoke also adds to the bad ass attitude of the image. It’s a very poetic image, it’s balanced nicely with the bright white hand emerging from the black clothing. It reminds me of Larry Clark’s Tulsa grainy images depicting the drug scene, he worked in similar lighting conditions to this image, which i can guess is in a home, no not natural light, only a strong household light above, no windows. This gives the impression that its either night time or they have barricaded themselves inside, natural light would create a sort of fresh air relief in this image which would have made it less enclosed and less intimidating. The fact that you can tell its in a home makes it feel quite claustrophobic for me which only adds to the unapproachable impression of the image.
