The first variable is camera angle.This effects the image because if the photo is taken at knee level it will make the person look big and strong while they might be the nicest person on the world
Next variable is lighting.Lighting plays a big role because if you shine the light on someone from the right their left side is going to have hard shadows and it will make the person look like their on the dark side.
The 3rd and final variable Is proximity. This will change how much of the person you see and how much of the details of their face,clothes etc you see.
The camera angle in this photo i think is face level but to the side a little bit. This will make the person show one side of itself. The lighting is above his head to the right. This makes the other side of him dark and seem mean.The proximity is is cut of just below his chest. This makes the picture look almost like a id photo.It looks like this photo is in a battlefield and he is in the army. He also wearing a grenade on his shoulder.Seems like he is looking far in the field for his enemy.
I really don't know what message they want to sent to the viewer but to me he looks like a mean person that has a lot of power.
