The YE083 is designed for the evaluation of the halftone reproduction of an electronic camera. Two 11-graduated counter current gray scales are arranged on a gray background(D=0.62) . The gray scales being graduated logarithmically (gamma = 0.45).The output signal of an optimal gamma-corrected camera yields two 11-graduated counter current linear step signals. The contrast range of the gray scale is 40:1.

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 0.86 14
9 1.06 9
10 1.31 5
11 1.65 2

The density of the white field between the gray scale is D=0.05 (reflectance = 89%).
