According to the vision theorist Athanassios Raftopoulos, all conscious visual attention in humans brings with it the activation of the cerebral circuits related to the memory and conceptualization. In this way, conscious attention always "injects perception with conceptual content".
Conscious vision, called "late vision", differs from pre-attentive processing (prior to conscious attention), called "early vision". Early vision is responsible for processing information into units, called proto-objects, to which conscious attention can be directed. The early vision, in Raftopoulos's theory, would be independent of memory and conceptualization (thus being cognitively impenetrable - not being altered by the application of concepts).
In metaphorical terms, it is as if conscious vision would always bring with it the act of "labeling" that for which attention is directed. The study of the theories of vision led me then to explore the way in which this same act of labeling the objects of the world in late vision also operates in the perception of photographs. The idea is to make visible the labeling that conscious attention operates on the elements of photographic images.
