Product details
Introduction to ITE 11 grayscale card
The ITE 11 level grayscale card YE083 is used for evaluating the color tone reproducibility of electronic cameras. Two 11 degree grayscale bars are arranged in opposite directions on a gray background (D=0.62), and the grayscale bars are scaled logarithmically (gamma=0.45). The output signal of an optimal gamma corrected camera produces two opposite 11 degree linear step signals. The contrast range of grayscale is 40:1.
