Photo technique: Get slightly off-axis with the camera, and turn
out any room lights. I then process thru Paint Shop Pro to tweak
the brightness and contrast. (I just got Photo Shop, but don't
know how to use it yet :-)

you can put a layer or two of toilet paper or tissue over the flash
lens to diffuse it's output.Makes for a better picture.
Why use a flash at all? Its not like this thing is moving, so a
picture in ambient light might look a lot better. The "magic eye" will
probably look better. I'll have to shoot a photo of my bridge and see
how it comes out.
The pros use a flood directed into an umbrella-shaped reflector made
of something like cotton sheeting to give a "soft" diffuse source of
light.
...Jim Thompson
many cameras will require the use of flash in indoor lighting conditions.
I have an old Sony Cybershot DSC-S70 and a (relatively) new Sony
DSC-T300. Both allow no flash, auto-flash and "red-eye", your choice.
The old one is better ;-)

they may "allow" not using the flash,but the image sensor may not have the
sensitivity to pick up enough light for a reasonable exposure,and you'd
lose detail,or contrast would suffer.
Plus,you would need a tripod or other solid camera support for the longer
exposure times.

I have both a tripod and a unipod. I got the latter only recently to
cope with 9 year old granddaughter's birthday party and the hundred

Now all I need is a remote control video camera to handle the karate
events

Manual control mode. You pick the shutter speed, f-stop, focus and even
ASA. A couple of test shots to tweak the settings and you've got it.

exposure times.
My Canon A-620 has a two second delay so you can press the shutter and
the tripod vibrations can die down.

Presuming you want proper portability (pull the kit around on a kart
smaller than a shopping basket), and reasonable video quality (stabilized
SD), it should be obtainable for maybe $5K or a bit less. Stabilized HD
would be about $500 to $2k more. Maybe a little less for plug in.

Sometime you might want to search (google, youtube) FPV R/C. They have
first person view radio control equipment where people operate radio control
vehicles, airplanes, and helicopters, (and sometimes blimps indoors) from a
camera mounted on the model. They often use video googles and a head
tracking device so when they turn their head the camera pans and tilts. I'm
not sure if they use accelerometers, gyroscopes or maybe both. I have a
video camera, transmitter, and receiver I plan to mount on a model heli or
plane hopefully this year. I don't have the pan and tilt mount but that's
not recommended for new fpv pilots. They also have GPS interfaces to give
you an on screen display of coordinates and some feature autopilot that uses
the GPS to fly your aircraft back to the take off point if it looses signal.
