The aperture is the exposed part of the camera lens, the opening through which beams of light slash to reach the celluloid. Its analogy with the human eye is only partial: apart from modelling human vision and complementing our perception, the camera radically transforms our way of seeing. The narrow focus of the journal Apertura is to explore the cinematic medium and the mechanisms of its influence, while its broader research spectrum embraces the critical discourse on visual culture institutionalized in the 1990s. Apertura wishes to offer itself as a forum for all those (theoretical critical, historical, inderdisciplinary and intermediary) approaches that contribute to a more nuanced problematization and understanding of the way images as cultural products work, and to exhibit, for exploration, the non-evident, the invisible.
