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.
Remark: We support Any customized test charts only if you have high resolution image and size.
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%).
