“Photographic depictions played a key role—though one little noticed and commented on at the time—in a newfound attention to novel motifs and to the transience of the atmosphere,” de Font-Réaulx argues. Placed on a page facing a seascape photo by Le Gray, Courbet’s 1869 painting The Wave clearly owes a debt to the photograph’s ability to capture the fleeting moment for the painter to capture once more.
