Pickard and Singh’s “micro-macro” pictures are composite portraits of the two candidates, in which each “pixel” of the bigger pictures is a miniature version of their opponent’s photo. In a very real sense, human vision is always pixelated, though, in that photons arrive first to our retinal photoreceptors: a mosaic of discrete neural units, each in possession of the tiniest window to the visual world. These minute windows, called receptive fields, are the trees making up the forest of your perception.
Just make sure that, come Tuesday, you don’t miss the forest for the trees.
