| Abstract: |
A film editing table includes a light source mounted away from the editor's sitting position, with a light guide transmitting the light to the film editing table's optics to produce images on the table's rear projection screen with a brightness and color temperature substantially the same as the images displayed in commercial theatres such that accurate color judgments can be made for animation film. The editing table can also be used to edit dailies of live action motion picture films. The light source is preferably a Xenon light source and the light guide is preferably a liquid light guide. The end of the guide from which the light emanates is movable along three axes, producing the brightest image possible.

I claim:
1. A film editing machine, comprising:
- film transport means for providing a film pathway;
- a light source that produces an illuminating light;
- light transmitting means for receiving light from the light source transmitting the light while shifting the color temperature of the light;
- optical transmission means for receiving the shifted light from the light transmitting means, further shifting the color of the light to a predetermined range, and directing it across the film pathway for producing a projected image; and
- a viewing screen that can display the projected image;
- wherein the light source is remotely mounted from the optical transmission means and the light transmitting means comprises a light guide that receives light from the light source at a first guide end and transmits that light to a second guide end adjacent the optical transmission means.
