Camera on lunar rover

There are many pictures taken while the Apollo 17 Lunar Rover was be
driven. Was the Hasselblad mounted and taking photos automatically
every few seconds?

There was a 16mm movie camera. The Hasselblads were purely hand-held
cameras. The LRV also had a television camera, but that was only useable
while the rover was stationary.

I was looking at my Lunar Surface Journal discs, and A17, magazine 138
and others, for instance, is obviously from a Hasselblad, yet there
are quite a few shots that appear to be taken while the rover was
moving. I assume Schmitt took these during the travel, right?

I'm pretty sure not. For one thing the quality is too high for the
16mm movie camera. Another thing, the magazine has other shots. For
instance, the first few shots on AS17-138 are close-ups of some rocks.
AS17-138-21038, -21053, etc, has to have been taken while stopped. But
the -21075 through 21095 appear to be taken from a moving rover. Then
there are a few while stopped, then 21100 through 21142 must have been
taken from the rover while moving again. etc.

I'm surprised they could get unblurred still photos from the moving
rover, considering how bumpy the movies taken from them showed the ride
to be. I imagine the very short exposures required in the brilliant
sunlight of the Moon helped, but still...

The photos I was talking about were on black and white negative film,
as opposed to the color transparencies. B&W negative film is a lot
"faster" than color transparencies, meaning it needs less light, so it
supports shorter exposures.

Surface, the film was either 80, 100 or 160 ASA - different sources
give different ratings -

Most sources give 160 for the color film. The B&W film should be
faster, which could be why it was used on the rover.

The Hassleblad cameras were used on the later rover traverses to
photograph the journey. IIRC 16mm footage was taken on A15 and A16,
though the camera did not function properly on 15. Perhaps in a move
to conserve 16mm film, they opted to use film magazines. During at
least two instances the LCRU uplinked TV during traverses. One on
Apollo 15, although it pointed at the ground, and on Apollo 17 as
Cernan parked the rover at its final resting position at the closeout
of the mission.

Yeah, Channel 7 Sydney invented RaceCam later
