Default Advice Sought: White Balance Issue?

Hi,

We have been shooting some video in school to help kids with their Maths.
Using a camcorder we have fixed the camera on a A4 piece of paper whilst the
teacher draws various mathematical diagrams. Our first attempt produced too
dark an image on the A4 paper so we borrowed a light from our Drama
department and used that to illuminate the paper.

The result was a much brighter image but as the hands moved around drawing
the diagram on the paper the brightness of the paper changed. I have tried
the colour balance filter in Liquid Edition which has improved the footage
but it's not brilliant.

Is there something that we haven't done correctly or at all?

All our footage was shot indoors using a Canon MV 500i camcorder.

Thanks,
Andy.


The silly but best answer is use a colour ed paper. You can get light gray paper
which will appear white on screen.

In the old B&W days (maybe it was colour, my memory is going!!), newsreaders etc
used yellow paper as straight white would always burn out even on the then
broadcast cameras.
