Immersion in salt water does strange things to skin, making it appear more lined, pasty and pallid. The eye squashed into the pressure of the mask looks years older than it would in its normal above-water state. The mouth is strained and lined with breathing through a valve. These reactions of the body to technological adaption and its environment, become more apparent when the photography is in black and white which removes the neutralising blue glow of the light-restrictive water. The thinness and fragile qualities of the skin, represented in tonal gradations, thus becomes far more apparent.
