It is equally noteworthy that the black-and-white portraits which make up the exceptions are for the most part single-figure images. In their apparent interchangeability with all other generic portrait photo- graphs, these photographs make the precarious condition of a resuscita- tion of traditional portraiture all the more evident. How then could one possibly explain the peculiar correspondence that governs these images, the fact that the portraits seem to succeed when presented in color and that the topographical images retain their highest credibility in the tradi- tional format of black-and-white photography?
