collected by Rembrandt, who was "probably inspired" to use surface tone by his example. Rembrandt used it in his late prints, from about 1647 onwards, and only in some impressions. It was one of a number of ways, notably including printing on different papers, and vellum, and using the burr from drypoint, that he used to vary the appearance of his etchings. In several impressions of his Flight into Egypt: A Night Piece (B. 53) surface tone covers most of the plate.
