    The YE 0223 is designed for evaluation of the halftone reproduction of electronic cameras. Two 13-graduated counter current gray scales are arranged on a gray background (D = 0.75), the gray scales being graduated logarithmically. Related to the densities of the gray scales: gamma = 0.45, related to the transmission values (brightness): gamma = 2.2, that being exactly the reciprocal value of gamma = 0.45. The output signal of a optimally gamma-corrected camera yields two 13-gratuated counter current linear step signals.

    The contrast range of the gray scales is 200 : 1.

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

     

    Step Density Reflectance in %
    1 0.05 89
    2 0.13 74
    3 0.22 60
    4 0.32 48
    5 0.43 37
    6 0.55 28
    7 0.69 20
    8 0.88 13
    9 1.06 8
    10 1.31 5
    11 1.65 2

     

    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 %).
