Settings and Configurationsd-lab.2, d-lab.2plus, netlab.2plus: Operation4.5.15.3 Parameter for Shift CorrectionApplies only to d-lab.2/2plusEffect:If the color density curves of a negative film are not precisely parallel to each other, theresult is a crossover color cast, i.e. an originally balanced light intensity for all colorsduring the exposure results in a color cast of one color in the light image areas and acomplementary color cast in the shadows. A neutral grayscale, for example, would show amagenta 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 impactas well as color trend) and on the film process.The shift correction is determined individually for every negative with respect to contrastand motif. By means of this correction the neutral area of the motif can be shifted in sucha way, that the colors in the important sections of the image come out neutral, whichmeans that the color trend in the image is considered less disturbing. The shift correctionhas no effect on negatives without a crossed-curves effect and no effect on artificial lightexposures.The K parameter influences the impact of the shift correction.Adjustment range: 0.0 to +4.0Step width: 0.1Standard setting: 1.0Making changes Press left or right Arrow button at K in theTFS Color screen to increase or decrease thevalue.099The impact of the color correction acts in proportion to the changes in the K-value. If, forexample, the value is increased from 1.0 to 1.5, the shift correction is 50% stronger.4-70 2005-05-01 / PN 04092_01 AgfaPhoto
