Some HBs were making ridiculous claims about the S-IVB being used to take Apollo photographs, so I was looking through the archives for photos and footage of the empty stage that, for obvious reasons, can't possibly have been taken by the S-IVB!
While doing that I looked at magazine AA from Apollo 17
That magazine captures several shots of Earth. One set is a pan across the face of Earth just after transposition. Then there is a sequence of frames after the S-IVB has been discarded, followed by a longer sequence of the empty rocket part floating off into the distance. The final couple of frames of the magazine show another view of Earth.
Two things should have happened between that view of Earth immediately after extraction anf the final shot: Earth should have receded further into the distance, and there is a possibility that (if the time gap is long enough) there should be some rotation.
Here are the two frames superimposed:
So the Earth is definitely smaller. Here's a segment of the two sequences and the same area in the 'blue marble' shot.
There is a long strip of cloud that has moved between the two frames (left and centre) and the 70mm Hasselblad view shows the cloud nearer the edge than the first 16mm view.
It's also worth comparing that later 16mm view with a composite of frames from the transposition sequence.
The view is different again, because they've only just 'gone for TLI',
Add that to the long list of details in the blue marble photograph that proves it was taken exactly when and where it was claimed to taken.
