3.2 SHADING

This "Shading" should be performed whenever the type of film is changed or

the mirror unit is moved.

When the projector unit is selected, shading should be done after selecting

the type of film. The shading should be done with a base film and the

N-correction filter for the negative films and with the P-correction filter

(without base film) for the positive films.

The N-correction filter corrects the color and intensity of the projected light.

The P-correction filter corrects the light intensity of the projected light so that

it becomes similar to that for the negative films.

When "Shading" is performed, the first scanner moves and stops under the

mirror unit. Then AGC (Auto Gain Control) for the light intensity from the

projector lamp is performed. Shading for black and white levels is also

performed after the AGC.
