The YE083 is designed to evaluate the halftone reproduction of electronic cameras. Arranged on the gray background are two 11-index counter-current gray scales (D = 0.62). Grayscale is on a logarithmic scale (γ = 0.45). The output signal of the best gamma correction camera produces two 11-step gradient convection linear step signals. Grayscale contrast ratio range is 40: 1.
