動態(tài)范圍測試卡用于測試色調(diào)響應，噪聲，基本分辨率和色差還原。當與Stepchart模塊使用時，可測試高密度范圍。
可用基材：半光，相紙，彩色LVT菲林。
動態(tài)范圍測試卡由Stepchart, Multicharts和 Multitest模塊支持。如果幾個手動曝光可用，該測試卡可用于動態(tài)范圍后期處理。Dmax> =3.4足以用于像素尺寸比較小的照相手機和數(shù)碼相機，但是該段單反通常具有更高的動態(tài)范圍（并也手動曝光），這使得它們非常適合動態(tài)范圍。
This 15-patch grayscale step chart has 12 of the patches in a somewhat elliptical arrangement on the periphery and three in an inside row. The relatively large patches are especially good for measuring noise. Supported by the Imatest Stepchart, Multicharts, and Multitest modules. Printed on 12x18 inch (305x457 mm) luster inkjet media.
Details
This 15-patch grayscale step chart has 12 of the patches in a somewhat elliptical arrangement on the periphery and three in an inside row. Nominal patch densities are 0.1, 0.19, 0.3, 0.41, 0.53, 0.66, 0.81, 0.97, 1.17, 1.39, 1.66, and 2.0 for the 12 peripheral patches and 0.77, 0.90, 1.05 for the three central patches. The relatively large patches are especially good for measuring noise. Supported by the Imatest Stepchart, Multicharts, and ColorTest modules.
The standard size has an active area of 11.4x17.1 inches (290x434 mm),printed on 12x18 inch (305x457 mm) luster (semigloss) inkjet media.
