Sineimage ColorChecker SG Chart for White Balance
| Material | HD photographic paper |
The new Digital ColorChecker Semi Gloss (SG) is specifically designed to meet the needs of digital photography. Check and compare the digital reproduction of a real scene or a test pattern, make a white balance with a digital camera, or use the chart with camera profiling software to create an ICC profile of your camera.
Designed to mirror all the colors you can see
• 140 patches chosen specifically for their location in color space expand the color gamut and allow you create profiles that capture the full capabilities of your digital camera and scanner.
• Includes standard ColorChecker chart colors. 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 color as their counterparts, but also reflect light the same way in all parts of the visible spectrum.
• More skin-tone reference colors deliver greater accuracy 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 8.5x11 inches (21.6 x 27.9 cm) easily fits into a full frame shot.
The colors of the ColorChecker SG were implemented in the "ProfilMaker" Digital Camera Modul.
Using the Digital ColorChecker Test Chart alone
1. Shoot the test chart under a reprographic setup (e.g.) lamps at approximately 45° to the Digital ColorChecker to reduce gloss reflections and use evenly distributed light with a stable color temperature.
2. Optimize the exposure so that the hoariest patch is in RGB range of 220 - 245.
3. Compare the monitor display (with a calibrated and profiled monitor) with the chart placed in a viewing booth. Make adjustment to the image until the image matches the chart in the viewing booth.
