While I have been in limbo with this project I have been reviewing some of my research. Jehad Nga is a photographer whose work I first saw at Paris Photo in November 2010. His style is often chiaroscuro and I think he does it very well. In his Turkana project he uses shafts of light to highlight the faces and the vibrant colours of the Turkana tribal outfits.
In Pirates, Inc-Somalia he balances different light sources beautifully. Take a look at it here - Jehad Nga.com
