3nh / Sineimage YE0153 Gray Scale Test Chart (11 steps) Grey Chart with 11 Patches 4:3 Gray test chart greytest chart


The YE0153 is designed for evaluation of the halftone reproduction of electronic cameras. Two 11-graduated counter current gray scales are arranged on a gray background (D=0.75), the gray scale being graduated logarithmically.

Related to the densities of the gray scales: gamma = 0.45

Related to the reflectance values (brightness): gamma = 2.2 , that being exactly the reciprocal value of gamma = 0.45.

The output signal of an optimally gamma-corrected camera yield two 11-graduates counter current linear step signals. The contrast range of the gray scales is 40 : 1.

The values of the 11-graduated gray scale are as follows:

 

StepDensityReflectance in %
10.0589
20.1374
30.2260
40.3248
50.4337
60.5528
70.6920
80.8813
91.068
101.315
111.652

 

The density values are based on BaSo4 = 0. Two black fields and a white field are located between the gray scales, the density of the black filed is D > 2.4 (reflectance < 0.5 %). The density of the white filed is D = 0.05 (reflectance = 89.9 %).
