These miniature charts have the same 18 color patches as the GretagMacbeth™ColorChecker®, plus 12 spectrally neutral gray patches to assess correct exposure and white balance in close­up or macro photography applications. The patches are mounted on aircraft grade anodized aluminum and are set below the top surface to help protect from damage.

Gloss: Gray patches have an extended dynamic range (density ~ 2.4) and are suitable for measuring camera imager noise. Specular reflections from the gloss surface may occur for illumination geometries less than 45°/0° when used without crossed polarizers.

 

Matte: Gray patches have a lower dynamic range (density ~ 1.6) but are more suited to narrow illumination geometries such as those used in endoscopic imaging or direct-on camera flash units. Because the matte surface can be interpreted as imager noise, we do not recommend using matte gray patch targets for evaluating imager noise in high magnification applications.
