I don't share your enthusiasm for his work. His approach is simplistic and as a result makes its subjects seem simplistic. There is a lot of photography of indigenous cultures that is much more connected to those cultures, and as a result, has more empathy as opposed to Borges' sympathy.
And a response from Tina Manley (http://main.nc.us/openstudio/tinamanley/) who photographs quite a bit in indigenous cultures:
I agree with Jeff here. Phil Borges' photographs are technically beautiful but seem emotionally dead. The people are viewed as curiousities and their differences are emphasized rather than their humanity. They are beautifully exposed and printed still lifes.
