TE83 D Gray Scale Test Chart Transparency

TE83 D Gray Scale Test Chart Transparency

Two 11-graduated counter current gray scales are arranged on a gray background (D = 0.62), the gray scales being graduated logarithmically (gamma = 0.45). The output signal of an optimal gamma-corrected camera yields two 11-graduates counter current linear step signals. The contrast range of the gray scale is 40:1.
 
The values of the 11-graduated gray scales are as follows:
