The image on the right does appear to show a hood over his head. I am still confident it is not though, and what you're seeing there is a distorted image from the shadow being cast over his forehead/left side face and the image being so enhanced.
Look at the image on the left. You see the white "washout" cylinder shape above his nose, covering his forehead and seemingly wraps up around the left side of his head and face.. This is the shadow people are confusing for a hat in the standard color images. It really blurs the image of the standard colored shots.
Looking at the image on the left you can see his hair pretty well. There is a point in the middle where you can clearly see his hair kind of parts to each side.
Once you start seeing the bright white "washout" spot above his nose that seemingly wraps around the left side of his forehead/face/head. Once you realize that is a shadow, not a physical piece of material ala hat or hood, you immediately get a much clearer vision of what you're actually seeing. You can then see the hair on his head.
Again if you look at the image on the left.. You can see the outline of the back/top of his jacket. You can see either the opening of a hood or just the back of his jacket is opened up a bit, but it clearly shows there is no hood coming up over his head. If there is a hood, it is falling behind/below his head, not over it. And that at the very top of his head what you're seeing is hair. Kind of parted in the middle.
The image on the right is much more confusing as it's more distorted and does create an illusion that looks like a hood over his head. But when you establish the pieces again, just like we did in the image on the left you will see that it's just an illusion created by that "washed out" bright white spot above his nose, on his forehead.
In the image on the left you can clearly see that the back of his jacket/hood runs behind his head. The image on the right is distorted making it appear the back of his jacket/hood is running up the back of his neck and over his head.
That bright white washout image in these shots is the shadow that creates the illusion of a hat in the standard color shots. That shadow is what has altered the entire perception of these images.
It's like an optical illusion image almost. Your brain is composing the final image you see based off the perception that shadow is a physical piece of material.. Once you see it once, the shadow, and realize it's not a physical material he's wearing, but a shadow casting over his forehead/face area, the whole image is then viewed differently. You then see the hair on his head.
My input has very little significance, I strongly encourage people to study the images for themselves. Follow over what I'm describing and I believe you will see it. I'm positive his head isn't covered and he has a head full of hair.
