During an exhibition, images displayed under the rubric of Latin-American photography vary according to the criteria retained by both curators and critics who legitimate their selection as well as their organisation. Curatorial biases can on their own determine choices with changing ethical and aesthetic implications and thus influence the shape taken on by exhibitions according to the thematic categories retained and the textual commentaries proposed for works whose Latin-American meanings, ever since the 1990s, are less affected by geographical considerations than by historical ones. In this thesis, it is our intention to show, first, how artists, using a plethora of plastic means, impart shape and form to experiences of time and, second, how images, through and according to the present moment, can establish various relationships with the past. Enlisting a semantic-pragmatic approach, we analyse the references established by images and texts in order to measure the contextual implications borne by their temporal relations; at the same time, the plastic modalities given to these temporalities allow us to interpret their meaning.
