On the third photo, the light is coming from all over because it is outside and filled with natural light. The gesture and position of the model is a head on image and it is a medium shot as it shows the waist up. The setting is a big field of grass, taken in China. The photographer seems to be 15ish feet away but is from a point of view that is head on and straight at the subject. The face can communicate that lighting and the position allows the viewer to really focus on the horn and face and have it contrast really well with the field behind. All of it brings the focus point at hand.
Potrait
The photo I chose is the bottom right one of Emma and Gwen. The lighting comes from the left and right side of the two to get maximum lighting so they can be focused on in front of the black screen. The models are situated head on and facing down as I am able to get a higher up angle to capture the image. The viewpoint is head on and a vertical photo. I am able to compare this to the one right above as the prop stays the same and focusing right on the subject as the focus point. They both contain the same subject and show different rotation as they lean to the left and right in the photos.
