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.

| Format | selectable |
| 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%).
