Wow, learned something.
Would be interesting to see real life vs television comparison of both with and without makeup...

Camera "shading" is a critical part of a broadcast-quality TV production.  The shader has a control panel for each camera where s/he can adjust lens iris, "pedestal" (a.k.a. DC offset in electronic terms), gain, offset, "gamma" (linearity) and "knee" (compression) for red and blue (green is the fixed reference).  The shader typically gets the best "broadcast reference" picture monitor to see the picture, as well as waveform and vectorscope to monitor the video waveform.  The shader has final responsibility for the quality of the video images.  The director "only" instructs the camera operators what shots to get and calls when each camera is switched into the program feed.

This shows a typical configuration for shading 16 cameras.  It is split in half because a single person can't handle shading 16 cameras by themselves.  The big knob at the bottom of each camera panel is a 2-axis "joystick". Forward-back controls the lens iris, and the knob on top rotates to adjust the "pedestal" (DC offset).

I would have a riot on my hands if I had only 2 operators to paint 16 camera's in one of my trucks........ the most I ask any single operator to handle is 4 camera's at a time for sport, maybe 6 for studio stuff, but there is also an Engineer on a master setup panel doing an overall setup across all of the camera's and he/she is tasked with making sure all of the various operators is keeping up and doing the right thing maintaining a standard.
We don't call them "Shaders" here in Australia, (although a couple of people I have hired might have been a bit shady, lol) they are simply CCU operators.  :-+

I understand that doctors are trained to say "there" instead of "uh-oh" or "oops".

Back in the mid 1970s, the state of the art broadcast color TV camera technology still used vacuum tubes for imaging (while everything else was solid-state).  So we still had to deal with these fragile (and frightfully expensive) things.  It was critical that you never allowed them to face down because of fear that any possible debris inside the tube could land on the imaging surface and mar the picture.  They were shipped in large cube shape boxes with an internal gimbal to keep the tube always facing up regardless of the orientation of the cardboard carton.

Tektronix made the same recommendation; do not store CRTs and do not transport oscilloscopes with the CRT face down.  CRTs which are otherwise in perfect shape can have debris inside which will damage the phosphor coating.

It's the cameramen who are shady, inside every cameraman there's an amateur pornographer. You only have to be in an OB truck, or on the bridge, watching the raw camera feeds to know that I'm right.  :)

In the U.K. We call them rack operators and they rack the cameras.

I was in a news OB outside the MOD during the Faulklands war. There was not much happening and the cameramen were just panning along the street looking at the girls walking by and zooming in on their upper bodies.

The female director got annoyed with this and said over the talkback 'Haven't you seen a pair of breasts before?' To which a cameraman replied 'Not those, no!'

I grew up with a pair of religious parents and every Sunday we used to watch a BBC programme called 'Songs of Praise' where they transmitted a church service from a different location each week. One Sunday we noticed that a camera kept on showing a pretty woman in a brightly coloured top and my father remarked "the cameraman likes that one". Fast forward ten minutes and the director switched cameras by accident to show the same woman's breasts in close-up.

Standard operating procedure for my father was to turn off the TV for the night if he saw anything that offended him, and for the first and only time 'Songs of Praise' was switched off mid programme.

I also remember a visit to Granada TV Studios in Manchester, and this was a technical tour rather than the tourist stuff that the general public gets to see. Two things that I recall about the 1980's cameras were a) their large size and b) the fact that Granada TV kept them all running 24/7 to avoid recalibrating them each time they were used. The power bill must have been substantial.

In the studio's we leave everything running 24/7 for a number of reasons, but the most important are failures due to thermal cycling and inrush currents and the other of course is reduced setup time.

"Have you been saved by Jesus?"
Once met Mormons in public transport. A dialogue like this happened:
Mormon: "Good evening to you. Do you have some faith ?"
Me: "Yes, I have a faith. I believe in non-existence of God."
Mormon was clearly nervous about this answer: "Wait, what ?"
Me: "I believe that no God exists."
Mormon: "But we have proves that God and Jesus act good."
Me: "Me belief is stronger than your proves."

Last two sentences were repeated in 3 cycles with no escape. It was ended by my terminus station. I hope they learned something. ;D

Biggest cost in a studio used to be the lights and the AC to keep the rest of the set from catching fire. The power for the cameras would be incidental, as those lights started at 1kW, and went up from there, and you might have had 15 or more on a set for general lighting, plus some spots that were used for fill in so the talent had a decent face shot without shadowing. With 30kW of light, and about the same for airconditioning to get the sensible heat out, who would notice a 2kW load for the cameras, and with a 5 hour or so warm up period before starting cal it would be just noise.

Just had some massmeters done, and took them to the lab the day before and plugged all in to warm up for 24 hours before the cal check, so they get stable.

 As someone who, in HS as part of the AV crew got to film the practices of the girl's gymnastics team, I refuse to divulge further information on the grounds that it may incriminate me. I will say there were many things that never actually got to the tape  :-DD  That was before VHS and Beta, open reel video tape and a rather large B&W only camera. I did eventually get to use a color system, videoed the school plays with that one.

You think that the recent incident will make people more willing to volunteer in the future?
