In this photo the surface of the water communicates inexactly the water’s depths, giving little indication of its temperature, the presence or absence of fish and other wildlife, the astringent or unctuous qualities of the substance itself in contact with human skin, the pressure imposed upon the eyelids or corneas of a person submerged, the float of clothes or trunks or breasts or genitals, the ragged irritating edge of jet ski engines, the creep of waves to the beaches on either side and the voices and footsteps of walkers and idlers. Each snapshot I take measures more of the unshown.
