产品介绍

动态范围测试卡用于测试色调响应,噪声,基本分辨率和色差还原。当与Stepchart模块使用时,可测试高密度范围。

可用基材:半光,相纸,彩色LVT菲林。

动态范围测试卡由Stepchart, MultichartsMultitest模块支持。如果几个手动曝光可用,该测试卡可用于动态范围后期处理。Dmax> =3.4足以用于像素尺寸比较小的照相手机和数码相机,但是该段单反通常具有更高的动态范围(并也手动曝光),这使得它们非常适合动态范围。

 

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.
