The ISA ColorGuage Micro Target has the identical 18 color patches as the GretagMacbeth™ ColorChecker®, plus 12 spectrally neutral gray patches to assess correct exposure and white balance in close-up or macro photography applications.

This is a professional grade miniaturised target for assessing colour, tone, and white balance in addition to measuring resolution and Spatial Frequency Response (SFR) or Modulation Transfer Function ( MTF) for digital cameras/scanners using edge gradient analysis of ISO 12233 and ISO 16067.

Gloss grey 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 45º/0º when used without crossed polarisers.
