mirror mirror on the wall (3)
I have argued that the distinction between specular and diffuse reflection only makes sense within the framework of the distinction between mirrors and non-mirrors. We can see objects which present a diffuse reflection even tough it should be theoretically impossible. Diffuse reflection determines the possibility of an object to become itself a mirror, but it does not play any role in our ability to see it or to be reflected by other mirrors.
How then do we see objects?
Imagine an object with an irregular surface reflecting rays in all directions. Obviously, it is also reflecting something to our eyes, otherwise we would not be able to see it. What is it then reflecting, and how?
Well, simply put, it is reflecting all the light that is falling on it, from all directions. That is why we can see it from any perspective.
At the same time, it is also reflecting rays the way geometric optics tells us it is, and one can assume that unless they somehow fall in our direction, that these rays will not play any role in our perception.
The problem with geometrical optics is that it is limited to single rays, while objects are, in general, illuminated by ambient light. Even lasers, not to mention spotlights, create beams that are too broad to be confined by geometrical optics. And for that, you don't even need to shrink your size like Ant Man.

The example of the artist under a spotlight confronts us with the question how light can reach our eyes without leaving any trace on the way. The obvious solution, that our eyes, or our cameras, are more sensitive than matter is difficult to entertain since nothing in our experience would justify such an explanation. A solution which is incompatible with both the Newtonian view and wave theory, is that black, or more precisely here, darkness, should be considered as a color, at least in a practical sense. Understood this way it becomes completely understandable that a bright spot can be seen surrounded by darkness. It would be exactly like watching a white spot on a red screen, except that the red has been replaced by a shade of black, or darkness.

This cannot be obviously the last word on darkness. The least of the implications is that such a view gives quite a twist to the idea of dark matter, or cosmic background radiation. But then, anything I could say on these subjects would be gratuitous speculation of a layman.
