I like Salgado, but I would not consider him an artist (who uses photography as a medium), but rather a photographer who strives to use aesthetic elements borrowed from classic arts. In his case, mostly Rembrandt-esque lighting, chiaroscuro.
If I dare continue along this path, I'd venture to say that most of us (myself certainly included) posting on this and similar forums belong to the same group of photographers (with various degrees of success, of course), trying to infuse elements of classical composition, balance, color contrast and harmony, etc. into our photographs.
