Digital Gray Card™
Also known as the DGC, this is a gray card for calibrating digital cameras.
The Digital Gray Card™ is a plastic card with a matte surface. The spectral response is flat across the spectrum, making this card useful for setting the neutral, or "white", balance for digital cameras in almost any illumination.
The Digital Gray Card™ is available in two sizes; the DGC-100 10x15 cm (approx. 4x6 in.) and the DGC-150 15x22.5 cm (approx. 6x9 in.).
Four measurements were averaged for this spectrum graph. The measurements were made with a GretagMacbeth Spectrolino® equipped with a D65 filter. The spectral data was acquired, averaged and analyzed with SpectraShop™SpectraShop™.
