The YE084 grayscale image is used to evaluate the halftone reproduction of an electronic camera. Two 11-level counter-current gray levels are arranged on a gray background (D ≈ 0.65), the gray level is linearly graded. Dependent on the gray level: γ = 1. The gray scale contrast range is 40: 1.
Eleven gray values are as follows:
step | density | Reflectance in% |
1 | 0.05 | 89 |
2 | 0.10 | 80 |
3 | 0.14 | 72 |
4 | 0.20 | 63 |
五 | 0.26 | 54 |
6 | 0.34 | 45 |
7 | 0.43 | 37 |
8 | 0.55 | 28 |
