As Matthew says, ". . . what, exactly, are we judging? . . ." Yes, indeed. A portrait of someone we are particular interested in should reveal individual personality or physical characteristics, or invoke memories. Karsh's famous portrait of Churchill deprived of his cigar recalls (to me) the great man's life from a dashing soldier to an aged statesman, and the panorama of England in WWII. But in Karsh's iconic photograph of Hemingway, I think not of Hemingway's literature or cultivated public persona, but of the intensity of the portrait. In Ruth Bernhard's nudes, the individual is nothing, but the lyrical image, "The Eternal Body," is all.
