The photographic image has assumed different classes of presence in the contemporary historiography, but it has still not taken the place of the writing completely. Also it is true that the photos can include an important quantity of meanings through which ones it is possible to arrive at a greater objectivity much more marked than other experiences of to say / to see (Guigou, 2001).
Sustained in that argument, this contribution tends to explain through one succession of images accompanied by a testimonial registry, the process that implied the gradual loss of the language, the historical conscience, the knowledge, the territory and the social cohesion of one of the last selk´nam woman so-called Angela Loij.
In synthesis and to the margin of theoretical discussions about the photography value in the historical speech, it´s clear that it may be an excellent resource to present and to expose the results of any social investigation in a formal and complementary plane with respect to the written information, constituting itself in one unquestionable possibility to transmit with greater fidelity the knowledge of the human diversity.
