It is a recurring idea nowadays in the study of vision that visual perception of objects occurs in two or more stages. After a visual stimulus, the initial stage of vision is usually described as the segregation of visual content in groups (through the connection of the lines that form edges) and the localization and orientation of these groups, distinguishing them from the background. The next stage of vision is related to the application of concepts to these visual elements, identifying them as physical objects. This is what we do at all times when we process visual information.

In Zenon Pylyshyn's theory, the processes that occur in the early vision are characterized as "pre-attentive" (subpersonal - occurring nonconsciously). The segregation of visual information into articulated units would precede the conscious action of paying attention to a specific physical object, and assigning to it a concept. When we apply a concept to something in our field of vision (as, for example, the concept of "table" to the object before me), the pre-attentive prosses of information has already occurred - as a condition of the possibility of this conscious perception.

In this essay, I separate the three layers of color that form the photographic image (made using the RGB system - Red-Green-Blue), in order to make the image viewer operate consciously (attentively) the articulation of the elements of the image in units. In this way, the work aims to bring to consciousness the visual process of segregation of visual stimuli into articulated units, which we constantly operate nonconsciously.
