The YE084 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≈0.65), the gray scales being graduated linear. Related to the densities of the gray scales: gamma = 1. The contrast range of the gray scales is 40:1.

Aspect ratio | 4:3 |
The values of the 11-graduated gray scales are the follows:
Step | Density | Reflectance in % |
1 | 0.05 | 89 |
2 | 0.10 | 80 |
3 | 0.14 | 72 |
4 | 0.20 | 63 |
5 | 0.26 | 54 |
6 | 0.34 | 45 |
7 | 0.43 | 37 |
8 | 0.55 | 28 |
9 | 0.71 | 19 |
10 | 0.96 | 11 |
11 | 1.65 | 2 |
The density of the white filed between the gray scales is D = 0.05 (reflectance = 89%).
