If you hook up a camcorder to a TV, turn it on (Image appears on screen), and face it at the screen, what is it showing?

When I tried it went blue, but I don't understand this.
The screen is showing what the camcorder is pointing at, but the camcorder is pointing at the screen, so..?

Yes, I get a hall of mirrors effect if I angle it slightly, but I am talking about facing it exactly at the screen, so that the hall of mirrors effect would be impossible, as the camcorder's whole view is the screen.

It is turning blue because the automatic adjustments for white balance and iris cannot make sense of the image so they work there way out of balance and toward an extreme. A CRT screen does have a color temperature which tends toward the blue end of the light spectrum but you will not likely notice it unless it is being exaggerated as is the case here.

If you turn off the automatic features of your camera (assuming your camera will allow this) then the video feedback will look more like a hall of mirrors effect.

It's the vid-cam hall of mirrors. Lots of fun, that one. If your screen goes blue, I'd guess that the vid-cam isn't getting a signal. Start with the cam facing something else, and the tape rolling. Many cams have a timer that turns off the vid-signal if no recording occurs after interval X - I'm guessing you coincidentally bumped up against that interval when you aimed the cam at the screen.

think of feedback from a pa system, but in video instead of sound. when you point a mic at a speaker its supposed to record the sound coming out of the speaker, but the speaker is supposed to play the sound the mic plays. but you still get a squeal. same thing here. even though theyre supposed to be reflecting each other, some colors still get in, whether from reflections, or anything else, and then it gets amplified and distorted. which gets you blue. or any other color (move it like half an inch and sometimes itll change colors). hope this helps!

This is video feedback. It's the video equivalent of holding a microphone too close to a speaker and getting a squeal.

This happens because whenn youre looking at the screen it shoaws you what your looking at so if you put youre camera in the tv your just looking at the tv..... ohh and have you ever notice some loghts going up that are horizonttal? look at the computer with it.
