The Light From Light
The existence of the light from light can be demonstrated by taking AD pictures with or without the lens cap, as long as all other conditions remain the same (the camera, the moment, the speed and the camera position).
Picture 1 shows two AD pictures taken to the Great Bear constellation at night in the same conditions, except one was taken without the lens cap (picture 1.A) and the other one with the lens cap (picture 1.B).
The AD picture taken with the lens cap shows colours and shapes, which demonstrates the existence of a type of light which is able to cross matter and leave a mark in the film roll. In the AD picture taken without the lens cap, not only is it possible to see the constellation, as you can also see the colours and shapes that were not perceptible to the human eye while taking the picture, but were captured by this photography technique.
