This series of Domino and Dylan is especially interesting because of the play of light and shadow. The sun both highlights with its beams and defines additional dimension in the shadows that it creates from its feline targets.
In the first picture, Domino's black and white is divided by the shadow and light. Dylan casts distinct images of himself in dark, distorted shapes with the exception of the one shot where he is illuminated by bursts of sunlight. In the last picture, Domino is shadowed ever-so-closely by her tail.
