Simplified ISO-15739 digital camera noise test chart

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 12″ x 18″ (305mm x 457mm) luster inkjet media.
