In this test, a piece of the scene is partially illuminated with a light that increases until one of the elements is shown in full.

The ability of light to modify and shape the way in which the same form is perceived is highlighted.

The light in photograph 1 reveals a small vertical area of the piece, unknowning the rest that is not illuminated and its complete form. You can guess that it will be slender or shallow, but it's just an idea that activates with our perception. In photograph 4, we are aware of the beginning and end of the piece, leaving no room for imagination.

This perception also affects the awareness and perception of the general space, which is revealed as a single dark and atmospheric space in photograph 1, and as a fragmented space in various environments in photograph 4.
