Designed to reflect all the colors you can see

• 140 color patches specifically chosen for their position in the color space expand the color gamut and allow you to create profiles that capture the full capabilities of digital cameras and scanners.

• Includes standard ColorChecker chart colors. Many of these squares represent particularly interesting natural objects, such as human skin, leaves, and blue skies. Not only do these squares have the same color as the corresponding squares, but they also reflect light the same way in all parts of the visible spectrum.

• More skin tones reference shades provide more precise consistency across a variety of skin tones.

•Grayscale blocks precisely control camera balance to remain neutral regardless of the light source.

• Sturdy, standard 295*226mm chart size suitable for full-frame shooting.

ColorChecker SG's colors are implemented in the "ProfilMaker" digital camera module.

Using ColorChecker Test Charts Alone

1. Shoot the test card under a copier light (for example) at an angle of about 45 degrees to the digital ColorChecker to reduce glossy reflections and use evenly distributed light with stable color temperature.

2. Optimize exposure so that the most transparent patches are in the RGB range of 220 to 245.

3. Compare the display of the monitor (with the calibrated and profiled monitor) to the chart placed in the viewing room. Adjust the image until the image matches the chart in the observation deck.
