We see two cases of splitting a face in half for the fishermen on pp. This strikes me as odd, trying to salvage a frame rather than making a statement photographically. How a picture this poor can up in such a collection mystifies me. This would be a much stronger collection if about a third of the photographs were simply left out. It looks as though the photographer was going for quantity.
Art is, of course, a matter of opinions.
The faces here and the expressions recorded are more often than not compelling. That is a shame, because it really should be much harder to take bad pictures of Yemenis.
