The following article intends to analize two latin-american art projects which seek to rethink identity through photography. The uruguayan project, Rostros Mixtos, works with portraits of immigrants and non-immigrants from Montevideo city and creates new (mixed) faces, allowing us to rethink migratory and cultural issues. The brasilian project, Humanae, creates a catalogue of “skin colors” guided by the Pantone® color scale, based in multiple portraits of people of different nationalities and ages; the result is a diverse cultural mosaic that questions the idea of race in Brasil. This article will revolve around the identitarian dimensión produced by these projects, parting from the compositive relation between the “ID photo” (the portraits) and the final collage or mosaic, and the way each part constitutes a whole, each time.
