Pair portraits

Our tutors have said to try and focus more on pairs in photography. In order to see how this looks in photography i feel researching this would benefit me.

Francois Brunelle:

Brunelle is a photographer who has had an interest in the human face since the age of 18 when he started out as a photographer. He has created a photographic series where he find complete strangers who look almost identical, as if they were real life twins. 

The theory that everyone has at least one or multiple doppelgangers in the world, other people that look almost identical to you is an interesting topic and this photographic series is very interesting considering that theory.
Portraits with pairs are very interesting to look at. You can get mixed messages through there faces one can be happy and one can look concerned, too serious or loving.
