The YE0153 grayscale test chart is used to evaluate the halftone reproduction of an electronic camera. Two 11-stage counter-current gray levels are arranged on a gray background (D = 0.75), the gray levels are logarithmically graded

Related to gray density: γ = 0.45
And reflectance value (brightness): γ = 2.2, happens to be the inverse of γ = 0.45.
One of the best gamma-corrected camera output signals produces two 11-graduate inverse current linear step signals. The contrast ratio of the gray scale is 40: 1.
Eleven gray values are as follows:
| step | density | Reflectance in% |
| 1 | 0.05 | 89 |
| 2 | 0.13 | 74 |
| 3 | 0.22 | 60 |
| 4 | 0.32 | 48 |
| 五 | 0.43 | 37 |
| 6 | 0.55 | 28 |
| 7 | 0.69 | 20 |
| 8 | 0.88 | 13 |
| 9 | 1.06 | 8 |
| 10 | 1.31 | 五 |
| 11 | 1.65 | 2 |
The density value is based on BaSo4 = 0. Two black fields and one white field are located between the grayscale, with black field density D> 2.4 (reflectivity <0.5%). White density D = 0.05 (reflectance = 89.9%).
Note: We only support any custom test chart only with high-resolution images and dimensions.
