I was intrigued enuff by Yesferatu's 'challenge' to provide an explanation for how the video camera pan-tracking of Apollo 16 was accomplished to spend the time onna google search to find it -- and coincidentally also managed to find an explanation for the televised image-phenomenon of flashing sparks not noted in previous televised non-tracking liftoffs (of Apollo 11, 12, 14 &/or 15).
My initial theory on how they managed to track the liftoff (of Apollo 16 and 17; while Apollo 15 was also equipped with a tilt-pan motor a technical issue prevented it from being used to track liftoff -- see below)was confirmed --ie., no big feat, since the cameras post Apollo 14 were fitted with a remote-controlled vertical/horizontal motorized gimbal, and the rate of ascent of the LAM could be readily determined (based on measurements of previous flights, Moon's gravity, mass of LAM and ascent thrust values) -- it only required a bit of trig. calculation using the camera-distance to synchronize the rate of camera motion speed with the LAM's accelerating liftoff (or working backwards, plotting optimal camera arc-second vertical motion relative to camera position-distance). I mean, I don't see this as a very problematic, overcomplex technical feat arguing for evidence of Moon Hoax.
But it turns out -- even with vastly-improved video-signal processing and control, an unforeseen glitch resulted in that the liftoff of Apollo 17 was NOT perfectly synchronized and the Lunar Ascent Module disappeared within seconds off the top field of view because the Rover (on which the video camera was mounted) was parked too close to the Lunar craft.
Re: the 'sparkly exhaust' cited: apparently referring to Apollo 15's liftoff as re: below. I thought it might have been the result of Moon dust (which is highly reflective, containing glassy nodules) having been deposited on the top of the Lunar Descent Stage (perhaps falling there off of Astronaut's suits while entering the upper stage Module and/or retrieving scientific instruments/specimens) OR ablative paint/insulation being blasted off by the (otherwise) invisible rocket motor exhaust, due to the non-visible flame characteristics of the Lunar Module fuel used: hydrazine and dinitrogen tetroxide -- an oxidizer). Turns out -- it WAS insulation. Perhaps this wasn't visible in other Apollo liftoff images (IF indeed it wasn't -- I don't recall) because difference in type or coating made the insulation more impervious to liftoff temperatures/pressures.

Liftoff
Of the most remembered shot from Apollo 15, I can still hear Walter Cronkite's voice in my head as he exclaimed, "Wow, look at that spectacular liftoff!" There was a display that looked as if roman candles were shot from the base of the stage lifting off. In actuality, pieces of insulation were ripped off and sent flying by the rocket blast, and they were colored brightly by a characteristic of the field sequential scheme. The color components for any objects moving in a scene will not register exactly, since they are imaged at different times. Liftoff showed this dramatically, with each piece of flying debris colored red, green, or blue.
Apollo 16 and 17
Two factors improved the quality of the television still more on the last Apollo missions. NASA's using the 210-foot dish stations of the Deep Space Network, which increased the signal strength by almost 8 dB, brought about the first improvement.
Image Transform, then a startup company in North Hollywood, brought about the other improvement. They demonstrated to NASA, using Apollo 15 footage, their new proprietary system for enhancing video. NASA had them bring their system online for Apollo 16. Now the converted video from all EVA's was shipped to California, enhanced, returned to Houston, and then distributed to the network pool, all in real time.
During Apollo 15 EVA's, the camera developed a clutch problem in the tilt axis. Flight control deemed it too risky to tilt the camera during liftoff to follow the ascent stage. For Apollo 16 and 17, however, flight controllers did track the ascent stage. With the punch button command arrangement and a 3 to 4 second time delay, their command sequence had to be totally preplanned. I had worked with Ed Fendell for the Apollo 17 liftoff to get it exactly right for a long tracking shot. At liftoff, the action was perfect, but soon the image of the ascending capsule drifted out at the top of the frame. Ed was furious that, after all the calculations, we missed the mark. It was discovered later that the crew had parked the Rover buggy closer to the Lunar Module than was prescribed by mission plan, and the vertical tilting of the camera was too slow.
Whenever I see a clip of that liftoff I note, as the stage nears the top of frame, a cut to a film shot of the stage ready to dock with the command module. And I still think, "Darn, we could have followed that final liftoff 'til it was but a dot of light winking out as it headed for the mother ship."
Incidentally: This website
http://www.astr.ua.edu/keel/space/apollo.html
provides numerous photographs, information and links re: optical tracking of Apollo flights by both amateur and professional astronomers, supplementing the abundant record of radio and telemetry communications/information, much of which was compiled by amateur enthusiasts -- and which is in itself a very comprehensive, independant resource affirming the actuality of the Apollo project evidence. I find it curious to the extreme that this validation of the fact of manned flights to the Moon is typically ignored or dismissed by those who endorse Moon hoax beliefs -- symptomatic (IMO) of gut-feeling replacing critical thinking.
I've made this observation before, but it bears repeating: I note the tendency of Moon hoax advocates to make far less use of available information and resources, and therefore being much less familiar with evidence re: reasonable certainty of Apollo accomplishments, than those who believe Apollo landings were genuine are familiar with evidence re: Moon Hoax.
I don't know how else to account for the persistence of extremely thin arguments and distorted claims that don't bear-up under even modest scrutiny. I haven't found a single Moon hoax claim that I can't explain, understand or otherwise account for.
Of course, I don't doubt there are and have been numerous conspiracies in almost all avenues of human endeaver, esp. public projects (as we discuss here on RI) -- and that NASA isn't exempt from having ITS secrets and frauds. But as far as hoaxing all Moon landings and the Apollo accomplishments -- I don't, can't buy it. My reasonable certainty is like 99.999... , as certain as I CAN be about something I don't have immediate, first-hand experience of.
All the evidence I've seen or considered in support of same is consistent and logically comprehensive.
Perhaps one of the more irrefutable, unfalsifiable 'proofs' taken in isolation, by itself, is the video imagery of moon dust following a discrete parabollic trajectory as it is flung off the moon rover's steelmesh-web tires -- this is ONLY possible in a vacuum, impossible to recreate in a sufficiently-large studio-stage to encompass the sheer scale of distances the video record consists of. (Though I suppose it's possible an argument could be made that a special surface could be made using moisture or chemicals to prevent dustclouds -- I just wouldn't find it convincing).
Oh: Another incidental. On landing, the Lunar lander, while generating a fairly modest 3000 lbs of thrust, is only 'pushing' on the Moon's surface equivalent to 1.5 lbs per square inch since the rocket exhaust chamber was 54 inches in diameter -- thus helping to explain minimum dust-displacement and lack of a significant crater. Due to lack of atmosphere, dust only several feet away from the exhaust thrust point of contact was relatively undisturbed (ie., about 2 inches thick, the moon-surface average, possibly a bit thicker from dust dislodged and settling due to landing.) Nevertheless, many photographs document that the Lunar Descent Module displaced dust precisely as one would expect.
This and other apparant Moon Hoax anomalies are explained at numerous Moon Hoax debunking sites, noteably here:

Hope this sheds some light on what has, for some, become a very murky issue.

PS: The 'shadows' issue has already been well-explained; For confirmation, simply look through personal photos taken with low-sun shadows of objects on rough uneven ground. Surface dips and rises WILL cause apparant non-parallel shadow displacements because the angle of sighting is relatively low. Depressions will cause shadows to appear further away (longer) and rises will cause shadows to be nearer (shorter) to the object casting them (relative to POV). As stated, from directly above, shadows will appear parallel (providing sufficient long distance from light source). The 'anomaly' is strictly an artifact of representing a three-dimensional surface in a two dimensional plane. Likewise 'simple', the lack of vivid foreground detail (Rover tracks) is the result of photographic reproduction/exposure technical limitations and optical properties.
