The journal Revelar, a title that points out at the same time a process (develop) and discovery (revelation), was born in 2015 from the 1st Encounters with Photography/FLUP, under the XIV Week of Art History -annual activity organized by students and teachers of the Faculty of Arts of the University of Porto. It is therefore a project immediately committed to a scientific field in which photography has advanced slowly by comparison with Architecture or the Fine Arts. ln the vast field of History of Art in Portugal, Photography has been absent, as it indeed was for the last thirty years within the national historiography. Photography is now advancing faster thanks to new profiles research, an increase in investment and safeguard of photographic collections and innovative fields of multi and interdisciplinary research that have been emerging.
