[QuadList] Need pedestal > was IO Tube Operations [Was Cronkite's first half-

[COURYHOUSE at aol.com]

Need pedestal for Museum's studio camera and head  too..  mid age Phillips 
ccd  camera but still  takes 2 people to  hoist it.  Maybe even a huge 
remote tripod with a  stout head...   suggestions?    if  you have some hardware 
availl or a  lead on some drop me a note of list.
Thanks Ed  _www.smecc.org_ (http://www.smecc.org)

Howdy  Gang,

I had the pleasure of cutting my 1V P-P "shadrack" teeth on RCA  TK-42s at 
WMVS-TV, Channel 10, at MATC in Milwaukee (Milwaukee Area Technical  
College). I recall them being monsters to move around the studio, but  very simple 
to "shade". Granted, the talent could light cigarettes in mid-air  with all 
the 1k lamps we had going!

I also remember the red "ped up -  ped down" toggle switch on the pan/tilt 
handle. Those cameras were so heavy  they used a motor to perform the move. 
If I'm not mistaken, when they replaced  'em with lead counterbalanced 
Vinten peds they sent the old ones to the auto  repair side of MATC. They used 
'em to build car hoists! ;-)

Best  regards,

John

Yes, it does look like everything  is clipped somewhat...although Walter in 
the studio shot doesn't look too  bad.
IO cameras had a pretty forgiving knee themselves....no artificial  
processing circuitry required. I don't really remember looking at a  grayscale 
chart on a TK-60 or 11, but I don't remember them having any real  problems with 
blacks....and we certainly weren't concerned with noise all  that much.
I think the advent of color....the TK-41 and   later....plumbicon cameras, 
which had no real knee on their own, made  getting the proper exposure a 
little more universal.
And Chris just  reminded me in his post that the early b/w IO cameras did 
not have iris  servos....so you had to light your scenes consistently and 
were stuck with  your initial f stop.  I don't remember ever telling the camera 
operator  to "reach around and stop that thing down a little!".  
We did "ride  the gain" for minor corrections however, as Chris pointed  
out.

Hi Guy,

Seems like the  entire dub was overexposed or just recorded with the gain 
too high. Look  at the commercials and see how overexposed they look. You 
know the  commercials (the cash register) were not overexposed!

Were IO  cameras overexposed to make up for poor black  reproduction?

Best,
Park
