So we have to add "Motion Blur" to the list of expressions, FoosM does not know.
Since you have trouble grasping the concept of "longer", that does not suprise me much.
There is no motion blur in those photos.
Some parts are out of focus.

The "photo in question" was taken on SO-168. (Note the magazine number:40) Like all of the surface color photographs.

The color film used by all the LM crews was SO-168 (HCEX) Ektachrome EF, high-speed color reversal film, ASA 160.
www.hq.nasa.gov...
That's a fine choice for multi-purpose color film. Excellent color with a fine grain.
But that isn't relevant to subject motion, shutter speed is all that matters. Do you honestly believe that Aldrin was moving as fast as a guitarists fingers and hands? I don't see any motion blur in your third example.

.
a shutter speed of 1/125 second. This was the typical shutter setting for Apollo photography

He probably set the camera at f/8 for cross-sun
Shutter speeds were typically 1/125 or 1/250 second. F-stop settings varied from f/5.6 for up-sun photos to f/8 and f/11 for cross-sun and down-sun photos.
An orientation for photography in which the sun is in front of the photographer and the subject is backlit. This frequently results in strong glare on the photograph.
In general the shutter speed was left at 1/250 second and the f-stop was set between f/5.6 and f/11 as needed for various lighting angles. Great care was taken to simplify the photographic operations.

Thanks, but I think I'll take the directions *printed on the actual film rolls* over what Clavius says. And besides, Clavius disagrees with itself:

That picture was almost certainly taken at f/5.6, 1/250th.

I originally thought it also was SO-168, thats why I used the 160 ASA examples.
However, when I double checked
www.lpi.usra.edu...
Which makes me wonder if they actually used 250 or 125.

Even though this video appears to be a ridicule, it also holds true many peoples beliefs around the moon landings. Most weather balloon operators that use VHF transponders would understand that it certainly would not have been difficult to circle around the earth in a stealth fashion. The above theory provides the concept that the LEM itself went on to the moon via remote control, as previously done with the surveyors, it had landed, relaunched via remote control perrished back onto the moons surface ( as promoted by NASA). As for the walk video production, they had cut to Nevada for pre recorded shots of the moon walk & live discussions were held in the capsule orbiting the earth.
Pre & post TLI this video explains how the astronauts circled the earth & let the LM go on to the moon, its the only possible way they could have done it with very little risk & 100% chance of coming back a success for all America to see. The LM itself went on to the moon via remote control the same way the Surveyors did from 1966 to 1969, You can see the LMs on the moon, however they are damaged, The returning LRO images will never be clear enough to show the Rovers, because they simply are not there. This video also concludes the fact that there is no sufficient Pre Apollo Bio test data available online, does this mean these tests came back with unfavorable results? THE USSR zond program revealed their tests... & not all were very convincing.

This cover up is starting to get more complicated and harder to do than actually going to the moon. I am starting to wonder what achievement would be greater, going to the moon or faking it.

You do understand how light works and how it reflects off the surrounding lunar surface and illuminates the shiny gold camera right?

The Far Ultraviolet Camera/Spectrograph was carried on Apollo 16. It used a 3-inch telescope to obtain images and spectra at wavelengths between 500 and 1600 Angstroms; (visible light corresponds to wavelengths of 4000-7000 Angstroms).
A far-ultraviolet camera/speqtrograph experiment was designed and constructed for studies of the terrestrial upper atmosphere and geocorona, the interplanetary medium, and celestial objects from the lunar surface. The experiment was successfully operated during the Apollo 16 mission 21–23 April 1972. Discussed are the design and operating principles of the instrument, the actual events and operations during the Apollo 16 mission, and also anomalies encountered and suggested improvements for future experiments of this type. This experiment demonstrated the utility of the electronographic technique in space astronomy, as well as the great potential of the lunar surface as a base for astronomical observations.

Apart from the fact that it looks composited in, couldn't they have a afforded just one c-stand...
...and a cutter instead of having to rely on the shade of the LM ?
Actually, instead of spending 1 hour all up setting up the flag, they could have used the flag pole and attached the cutter to that. This is basic, basic stuff in the film world.

Sourced from NASA Lunar Surface Journal - Apollo 12
David Woods writes in the Apollo Flight Journal: "To save size, weight and power consumption, the TV camera on board the CM had only one imaging tube, rather than the three or four found in contemporary colour cameras.

Sourced from: Experiment Operations During Apollo EVAs
the shadowed area behind the LM was considerably smaller than anticipated and the camera was located closer to the LM than originally planned. Hence, its field of view was somewhat restricted.
...thus eliminating two of the planned targets due to occultation by the LM.
The cable lines did not lay flat and tangled up in the CDR's legs almost every time he approached the camera. Fortunately, the battery moved rather than the camera.
It was moved even closer for EVA 2 and again for EVA 3 after the sun rose high enough to shine on it, thus eliminating two of the planned targets due to occultation by the LM.
...and the occasional camera moves to keep the camera in the LM shadow, it used more EVA time than anticipated.
Once each operation was accomplished, the astronaut was to leave the vicinity of the camera as soon as possible due to the venting of waste gasses from the PLSS which could increase the local ambient pressure, thus causing the camera to stop operating
