The name comes from the official term "Century stand", which in turn comes from the earliest days of filmmaking, when the Sun was the only major source of lighting; reflectors were used to keep the light on actors. The most popular size of reflector was the 100-inch "Century"; a progenitor of today's C-stand was used to hold it up.
The Century stand is near-ubiquitous on motion picture sets because of its modular nature and versatility. Its primary purpose is to position various flags, color gels, bounce cards, and silks in front of light sources to block, direct, or modify the nature of the light. However, it can also be used to mount small lights and rig anything that can be made to fit on the stand.

Well, if they were worried about the weight of a tube in a TV camera ... I think 22kg could be considered extremely heavy

Yep, I proved two major proton events occurred during Apollo. What have you done?
Obviously they didnt care about the five major flares during Apollo 12, so whether or not they did monitor for them, it didnt matter did it.
In photography and cinematography, available light or ambient light refers to any source of light that is not explicitly supplied by the photographer for the purpose of taking photos...The use of available light may pose a challenge for a photographer. The brightness and direction of the light is often not adjustable, except perhaps for indoor lighting. This will limit the selection of shutter speeds, and may require the use of shades or reflectors to manipulate the light. It can also influence the time, location, and even orientation of the photo shoot to obtain the desired lighting conditions. Available light can often also produce a color cast with color photography.
Shadows were one of the first things Apollo 11 astronaut Neil Armstrong mentioned when he stepped onto the surface of the moon. "It's quite dark here in the shadow [of the lunar module] and a little hard for me to see that I have good footing," he radioed to Earth.
The Eagle had touched down on the Sea of Tranquility with its external equipment locker, a stowage compartment called "MESA," in the shadow of the spacecraft. Although the sun was blazing down around them, Armstrong and Buzz Aldrin had to work in the dark to deploy their TV camera and various geology tools.
"It is very easy to see in the shadows after you adapt for a while," noted Armstrong. But, added Aldrin, "continually moving back and forth from sunlight to shadow should be avoided because it's going to cost you some time in perception ability."
The sleeve made its own little shadow, so "Al was looking at it, trying to see inside. And he couldn't get the tool in and couldn't get it released--and he couldn't see it," recalls Mitchell.
"Remember," adds Mitchell, "on the lunar surface there's no air to refract light--so unless you've got direct sunlight, there's no way in hell you can see anything. It was just pitch black. That's an amazing phenomenon on an airless planet."
ASA (film speed) determines how much light has to be let into the camera to make a correct exposure. Controlling factors on allowing light to hit the film are shutter speed, f-stop, and available light.
If your lens has a maximum opening of f-5.6 or f-8.0, then you have a slow lens and will need a higher ASA film. Lighting conditions will also combine to determine film speed. Generally, low light requires ASA 400 or higher. Bright sun conditions will allow you to use a lower-speed film. Another consideration is that the higher the ASA, the lower the quality of the photo.
If you are shooting landscapes or scenics with no action, in low light, or with your camera on a tripod, then you can use a slow shutter speed along with a low ASA film.
The basic rule on shutter speed is this: the more motion (that either you or the subject has), the faster your shutter speed should be
Dark Shadows
On the next sunny day, step outdoors and look inside your shadow. It's not very dark, is it? Grass, sidewalk, toes--whatever's in there, you can see quite well.
Your shadow's inner light comes from the sky. Molecules in Earth's atmosphere scatter sunlight (blue more than red) in all directions, and some of that light lands in your shadow. Look at your shadowed footprints on fresh sunlit snow: they are blue!
Without the blue sky, your shadow would be eerily dark, like a piece of night following you around. Weird. Yet that's exactly how it is on the Moon.
To visualize the experience of Apollo astronauts, imagine the sky turning completely and utterly black while the sun continues to glare. Your silhouette darkens, telling you "you're not on Earth anymore."
If we are photographing a subject that is moving quickly (athletes, dancers, playing dogs), we may want to eliminate motion blur. In bright light, we can do this by picking a fast shutter speed. In dark and fair ambient light, using a fast shutter speed is not always possible. Instead, we can freeze motion by making flash the dominant light source.
The whole reason that most people activate their flash units is because there isn't enough ambient light for the camera to capture a good exposure of the subject.
Since you don't want your photo appearing completely under exposed, the solution is to add some light to the scene with an electronic flash.
Activating the flash will also ensure that you can use a moderately fast shutter speed setting in order to freeze the motion of your subject.
But with slow sync flash you intentionally use a SLOW shutter speed in conjunction with the flash in order to add some motion blur to your flash photos.

8. The toughest moonwalk task? Planting the flag. NASA’s studies suggested that the lunar soil was soft, but Armstrong and Aldrin found the surface to be a thin wisp of dust over hard rock. They managed to drive the flagpole a few inches into the ground and film it for broadcast, and then took care not to accidentally knock it over.

Now notice how it begins dark and all of a sudden it goes bright like
the light behind the LM was slowly turned on allowing us to see Neil.
Now Neil did not have the resources to manipulate the light, nor orient himself to shoot the best photo since he had no viewfinder to determine how his shots would look like. Not to forget, he was on the clock.
During the lunar surface extravehicular activity, the commander will be filmed by the LM pilot with the LM 16mm camera at normal or near-normal frame rates (24 and 12 fps), but when he leaves the LM to join the commander, he will switch to a one frame-per-second rate. The camera will be mounted inside the LM looking through the right-hand window.www.msss.com...

When you watch the videos:
.....
Neil, if he was taking photos, is in full sunlight.
He is lit up like the human torch. In other words, the camera
would be getting all kinds of light going into the lens.
Neil is also paying attention to Buzz's exit, helping him out,
and Capcom has a conversation with him.
This is not a guy focused on photography, he doesn't even remark that he is taking photos.
Statements from the Moon Landing Believers. From pages 1 - 50 of this thread.
this guy might actually be a little dim.
I was laughing, cryind and my soul just died a little.
Listening to this guy with a horrendous voice whining
I agree on the whiny voice.
pissed all over by spotty oiks on the internet
F**k now who do we believe.
He is a shyster
you will see he is just S*&T.
Is English not your first language?
Does this mean the 1200 Jews he saved from the camps were a hoax
A whiny explanation
It's sad when folks are born without a brain...
be afraid, very afraid
Get off your backside.
is a moron.
his altar of inanity
He is a con-man spreading lies about America
I'll bet you're a Nibiru believer.
Sometimes I think u must be retarded:
Good God, how old are you?
How old are you?
You are showing your age
Their prolly either 14 year old sensationalists
they've recently had the internet installed in mental institutions.
It beats kicking the dog
Are you lying
a lot of dumbasses will fall for your trickeries
I'm going to ignore the fatuousness
BWHAAAHAAAHAAA!!!!!
it may come back to bite you in the ass
What a rotten, vile POS you are.
with your vile tactics
bit in the ass once again
Woo, Woo...Doo-Doo, Doo-Doo
Along with these...!!!!!!!!!!
Apollo "hoax" conspiracy whack-a-doodles
you may have insulted three-year-olds!
you speak Doofus quite fluently.
sucks balls
What in the hell is wrong with you?
ever been checked for dyslexia?
you should have a doctor check you.
the only "sleaze" going on is in the Moon "hoax" camp. (hehe)
It's just that whiny voice; it makes my hair hurt!

As usual, you have missed my point. You were trying to assert that NASA was in complete control of everything and therefore could have done what they liked. I pointed out that the CSIRO designed the horns that increased the sensitivity of the s-band equipment.
You havent demostrated that any SPE occurred that breached NASA's safety limits. Until you do so you have no argument.

What low light situation? They were there during daytime in full sunlight.

Wrong. 'Obviously',as you have been told on numerous occasions, the light reflecting off the Lunar surface around him is in turn being reflected off his suit. Hardly complicated, apart from for you

What the hell are you going on about now Foos? No light was turned on behind Neil, it's obvious that the aperture size was increased on the camera. Why do you think Neil is operating it? He's on the ladder Foos! The camera is in the LM behind the window being operated by Buzz
Still waiting for you to comment from the information I posted a few weeks ago Foos, the actual radiation data from both the Van Allen Belts and from outside of the Magnetosphere's protection, the data that was gathered by nations other than the USA. You know, the data that blows your dumb radiation theories out of the water..

First point: You can't compare video to photographs. While you may know the aperture of the lens in the video, you have no idea what the exposure time or sensitivity is.
Second point: You can't use random photos from Flickr as an example because you have no idea what post processing was done on them (I'm relatively certain SOME amount of post processing was done to all those photos).

Remember how I said the background would look over exposed? Thank you foe illustrating my point. Of course in the color photos the blue fill light of earthshine is more apparent. By the way, I guess they did bring a little telescope along with them after all. Are you going to cede at least that point?
The FLIKR examples simply show that when using 1/250 with slow film speed requires flash in low light conditions.
