Below is an extract from the tutorial covering how to set up correct tonal correction for film separation.

TONAL CORRECTIONS

Once you have rotated and cropped the image you need to check the image’s histogram to make sure that appropriate levels for the white and black points were captured.

Either select the Histogram option under the Image menu or select Levels from the Image>Adjust sub menu. The histogram report will give you a graphic indication of the amount of pixels from white through to black. You cannot do any adjustments within the histogram unit, but by using the Levels command you can fine tune the tonal distribution between the white and black points as displayed by the Histogram.

The easiest way to set the correct white and black levels is to double click the white and black eyedroppers and type in the following:
