The next image I took of this man, after I showed him a picture of his child was a warm smile. I like this image because it speaks to me of the protecting aspect of parenthood.
Great intensity in this image exemplified by the distrustful, angry look of the father as you snap his picture and the innocence of the child peering at this father. The child, focused on the father and basically unaware of his surroundings, does put the parent in protective mode, as well it should.
