AS16-113-18294 shows Apollo 16's CSM Casper above Dufay B' (near the upper right corner) and Valier (lower left corner). The dark "triangle" in the upper right corner is the silhouette of LM Orions window-margin. Source: Kipp Teague's Project Apollo Archive.
AS16-M-0033 is Apollo 16's Mapping/Metric Fairchild photograph of reflected light inside shadowed Dufay B (Dufay B is the crater near the center of the photograph's left margin). It's very interesting to observe the small craterlet at Dufay B's northeastern rim, which shows much more reflected light compared to the western inner slopes of Dufay B itself.

Neat elongated depression to the west-northwest of Dufay (between Dufay and Mandel'shtam); at 6°10' North/ 167°10' East (see page 135 in the Revised Edition of the Clementine Atlas of the Moon, Cambridge 2012). - DannyCaes DannyCaes Feb 9, 2014
Apollo 16's orbital panoramic ITEK-camera frames AS16-P-4127 and 4132 show close-ups of the elongated depression west-northwest of Dufay.- DannyCaes DannyCaes Feb 9, 2014

Jean Claude Barthélemy Dufay (July 18, 1896 - November 6, 1967) was a French astronomer. During his career he studied nebulae, interstellar matter, the night sky and cometary physics. In 1925, while working in collaboration with Jean Cabannes, he computed the altitude of the Earth's ozone layer.
Perhaps also interesting to know: the Dufaycolor process for photography and film, invented by Louis Dufay in 1908.- DannyCaes DannyCaes Feb 9, 2014
The name Dufay is also mentioned (although briefly) on page 184 of V.A.Firsoff's book The Old Moon and the New (Sidgwick & Jackson, 1969) in the chapter Seeing is Believing, about lunar observations performed through color filters.- DannyCaes DannyCaes Feb 9, 2014
