I have been reading my instruction manual for the Fuji F10 and I have not been able to figure out how to adjust the custom white balance. Obviously, I am an amature.

The instructions say to hold a piece of white paper under the light source so that it fills the entire LCD monitor.... I am not exactly sure what that means. Do I have to hold the piece a paper under a light and take a picture of it? Or do I hold the piece of paper in front of the camera so that it covers the LCD monitor?

I know my question sounds stupid... Like I said, I am an amature.
