About: Kodak IT8 Target 35mm
Kodak Professional IT8 Target on Ektachrome film, 35mm Transparency
IT8 targets are used to calibrate scanners and other color devices. You can purchase both reflective and transparency IT8.7 targets. These targets are basically precision photographic images that provide the following carefully-defined sets of color patches according to internationally accepted specifications:
* A set of 108 standard "conservative" color patches that are likely to fall within most device-color gamuts. These patches are located in columns 1-3, 5-7, and 9-11.
* A standard neutral lightness scale
* Target-specific color patches, many at the gamut limits of the colorants used to produce each target
* Each target also contains vendor-specific material - additional patches or images
The color values of the 108 standard patches are specified in terms of device-independent CIELAB color, otherwise known as the L*a*b* color space, or in Photoshop simply as Lab. The color values of the other patches are specified in terms of the colorants (photographic dyes) used in specific targets.
