Photography

My own eyes are no more than scouts on a preliminary search, or the camera's eye may entirely change my idea.

The image (shadow) being inverted depends on there being an aperture at the cross-over and the image (shadow) being distant. The explanation lies in the aperture.
The image (shadow): The light reaches the person shining like an arrow. The lowest [light] that reaches the person is the highest [in the image] and the highest [light] that reaches the person is the lowest [in the image]. The feet conceal the lowest light and therefore become the image (shadow) at the top. The head conceals the highest light and therefore becomes the image (shadow) at the bottom.

You put your camera around your neck in the morning, along with putting on your shoes, and there it is, an appendage of the body that shares your life with you. The camera is an instrument that teaches people how to see without a camera.
