Help, Building my own Teleprompter at DVinfo.net

Hello,

I ordered a teleprompter mirror and have been playing around with it and an LCD in front of my camera.

The mirror is at an angle, I can see the text fine and the video image is coming through fine but there is a slight blue tint to the video image.

Upon investigation, the LCD screen even though being all black, is really emmiting a blue tone.

I tried video card settings to take all of the color saturation out, but the screen itself seems to represent black this way.

When I balance to 5600k everything is fine.

The problem is most of my lights are Lowel and 3200k.

Any ideas?

Has anybody else run into this when using a teleprompter?

Thanks

Put a reddish or warm-color gel over the LCD to kill the blues. Easiest solution. Doesn't even have to be a true gel. Get one of the transparent report covers from an office supply in either red, orange, or yellow, and use that.

Thanks Martin.

I tried some gels, but what seemed to work was a little more attention to white balance and a white balance adjustment by a few degrees.

Also changing the back covering to a black material.

Everything is working well now.
