Following the TransEarth injection burn over the lunar farside, the crew experienced a fantastic view of the Moon from a perspective not visible from Earth (photograph taken through the 80mm lens).

From the mission transcript after TransEarth injection:

138:02:36 Cernan: Joe, this is incredible. That thing [the Moon] is getting rounder and rounder and rounder and smaller all the time. 138:02:40 Engle (Mission Control): Rog, Gene-o. Understand. 138:02:46 Cernan: The real show is on the inside here; it’s like three monkeys in a string pod. [...]. 138:04:49 Cernan: Hey, Joe, the Moon is almost small enough now where I can see the whole thing from the top, one corner of my forward window to the other corner of my forward window. [...]. 138:05:32 Engle: You guys are really hauling the mail out there. [...]. 138:08:33 Cernan: Hey, Joe, down at 9 miles [16.7 km] has to be exciting, but this has got to be unbelievable. The wind - the Moon now is well within the boundaries of my forward rendezvous window. [...]. 138:10:21 Cernan: See what I mean about size, Joe. It just about fills up, roundwise, right smack in the hatch window. Boy, and is this a full Moon, I’ll tell you. 138:10:39 Engle: You’re just about 1,400 [nautical] miles [2,600 km] out now, Gene.
