[lac-streams] A cheat list for the camera ops from Herman (camera geek)

[Herman Robak]

(Revised dos and don'ts)

The Sony cameras in the auditorium have sufficient manual controls
for our needs, I'm summarising the dos and don'ts here.

NOTE: There is no quick and convenient way to match the colour balance on
the fly, so leave those settings locked, PLEASE (more on that below).

NOTE 2: The spotlights in the front will have blue filters to match the
   "daylight" colour of the projection screen.  So the speaker cam will see
   things that are more "bluish" than the audience.  We want both cameras to
   have a fairly neutral colour balance, so cuts between them don't bring a
   jarring change in the overall colour. (more on that below)


	CHEAT SHEETS:

   Settings, SPEAKER camera (with spotlights):

Shutter speed: 1/25 sec
Iris/gain:     2.4/0dB
White balance: Balanced manually on the projector screen or a sheet)
        (spot lights with blue filters, or a gray/white projector image)
Img stabilise: OFF
auto/man lock: HOLD
Focus:	       Manual, push to focus

   Settings, AUDIENCE camera:

Shutter speed: 1/25 sec
Iris/gain:     open/+3dB
White balance: Balanced manually on the projector screen
        (room lighting only, the projector turned off)
Img stabilise: OFF
auto/man lock: HOLD
Focus:	       Manual, push to focus

	(end cheat sheets)


      Do this:

Leave the exposure settings locked down.  Use the "HOLD" position
(lower position, white letters) of the switch in the upper right corner
of the left side of the camera.

SPEAKER cam: Set and forget the focus on the speaker manually (tip: use
"push focus") once, and leave it.

AUDIENCE cam: Beware of focus!  Either use autofocus or push to focus when
appropriate. (if you don't understand "when appropriate", use autofocus



      Don't do this:

Don't set the exposure and white balance to auto.  Leave it locked!

Don't change the exposure or colour balance just because it looks slightly
wrong on the camera monitor.  The camera monitor is _not_ a good indicator
of colour balance and exposure!  The exposure and white balance will be set
and locked down in advance.

Do not enable the "steadyshot" (image stabiliser) feature.  The camera is
on a tripod.  If you move the camera, you mean it!  Stabilisers are
intended for handheld operation.

DO NOT use the "progressive scan" mode: It outputs 12 frames per second;
it's useless!
