    The YE0153 is designed for evaluation of the halftone reproduction of electronic cameras. Two 11-graduated counter current gray scales are arranged on a gray background (D=0.75), the gray scale being graduated logarithmically.

    Related to the densities of the gray scales: gamma = 0.45

    Related to the reflectance values (brightness): gamma = 2.2 , that being exactly the reciprocal value of gamma = 0.45.

    The output signal of an optimally gamma-corrected camera yield two 11-graduates counter current linear step signals. The contrast range of the gray scales is 40 : 1.

    The values of the 11-graduated gray scale are as follows:


    StepDensityReflectance in %
    10.0589
    20.1374
    30.2260
    40.3248
    50.4337
    60.5528
    70.6920
    80.8813
    91.068
    101.315
    111.652

    The density values are based on BaSo4 = 0. Two black fields and a white field are located between the gray scales, the density of the black filed is D > 2.4 (reflectance < 0.5 %). The density of the white filed is D = 0.05 (reflectance = 89.9 %).
