“…In Brazil, these images are recognized as a documentary source and are seen as illustrations of the history of engineering and architecture (Toledo, 1987;Reis Filho, 1989), and for this reason can even be examined as a detailed record of urban transformations and architectural interventions (Ferrez et al, 1983;Kossoy, 1984). At the same time, some relevant work has been done on the photographic record of engineering projects (Turazzi, 1996(Turazzi, , 2006(Turazzi, , 2012Mello, 2015), scientific expeditions (Thielen et al, 2002;Mello, Pires-Alves, 2009) and movements toward a visual representation of the city and its reception (Lima, Carvalho, 1997). However, in this country there have been no systematic studies along this line of research with regard to the visual standards adopted in engineering, including photography as a technical resource.…”
