4.5.15.3 Parameter for Shift Correction
Applies only to d-lab.2/2plus
Effect:
If the color density curves of a negative film are not precisely parallel to each other, the
result is a crossover color cast, i.e. an originally balanced light intensity for all colors
during the exposure results in a color cast of one color in the light image areas and a
complementary color cast in the shadows. A neutral grayscale, for example, would show a
magenta color cast in the light areas (lights) and a green color cast in the dark areas
(shadows). The shift characteristics depend on the respective film type (regarding impact
as well as color trend) and on the film process.
The shift correction is determined individually for every negative with respect to contrast
and motif. By means of this correction the neutral area of the motif can be shifted in such
a way, that the colors in the important sections of the image come out neutral, which
means that the color trend in the image is considered less disturbing. The shift correction
has no effect on negatives without a crossed-curves effect and no effect on artificial light
exposures.
The K parameter influences the impact of the shift correction.

The impact of the color correction acts in proportion to the changes in the K-value. If, for
example, the value is increased from 1.0 to 1.5, the shift correction is 50% stronger.
