A fantastic view of the Earth, centered on Africa, Madagascar and Antarctica was taken by Eugene Cernan through the 250mm telephoto lens as the crew was in the Moon’s gravitational sphere of influence about 379,000 km from home and about 28,000 km of the Moon before lunar orbit insertion.

“With something of the sadness felt as loved ones age, we see the full Earth change to half. [...] The line of night crosses water, land, and cloud, sending its armies of shadows ahead. We see that night, like time itself, masks but does not destroy beauty.”
Harrison Schmitt (NASA SP-350, p. 265).

From the mission transcript when the photograph was taken:
082:33:32 - This is Apollo Control. Apollo 17 now 14,948 nautical miles [27,684 km] from the Moon. And CapCom Bob Parker just advising the crew that we will not require a midcourse correction prior to Lunar Orbit Insertion. The Flight Dynamics Officer had been reviewing tracking data and establishing another vector, as he calls it, on the trajectory based on that last vector and it appeared that a midcourse correction of something less than a half of foot per second would be required, if performed. And Flight Director Gene Kranz, made the decision to cancel the midcourse correction prior to Lunar Orbit Insertion.
