La photographie sous-marine : étude sur l'état actuel de la question et sur les difficultés qu'elle présente
A late nineteenth-century French treatise on underwater photography by Pierre Guichard, published in Paris by Charles Mendel in 1899, written as a technical study of the state of the art and its difficulties. Its plates are halftone and line illustrations showing apparatus, divers and submerged scenes, giving a designer a record of early experiments in capturing images beneath the water. The grainy, hazy tonal photographs of diver, fish and a man gripping a pole suggest murky, low-contrast underwater atmospheres worth studying for texture and mood.
