ColorChecker SG info (from GretagMacbeth)
140 patches chosen specifically for their location in colour space expand the colour gamut and allow you to create profiles that capture the full capabilities of your digital camera and scanner.
Includes standard ColorChecker chart colours. Many of these squares represent natural objects of special interest, such as human skin, foliage and blue sky. These squares are not only the same colour as their counterparts, but also reflect light the same way in all parts of the visible spectrum.
More skin-tone reference colours deliver greater accuracy and consistency over a wide variety of skin tones.
Gray scale steps provide accurate control of camera balance and maintain a neutral aspect regardless of light source.
Sturdy, standardized target size of 8.5 x 11 inches (21.6 x 27.9 cm) easily fits into a full frame shot.
