The Gary Fong Color Reference Kit was created for photographers who are looking to gain spot on accuracy for both color balance and exposure control. The kit includes the White Dome, the Gray Dome, an intuitive pocket field guide and a convenient lanyard to keep everything together. By employing the quick and easy techniques of reflective metering with the Gray Dome and incident metering with the White Dome, color casts and inconsistencies will be a thing of the past. Unlike traditional white balance cards, the Gray Dome and the White Dome are spherical, gauging all types of light from all directions, which is essential for an accurate white balance sampling. Furthermore, they won't bend, warp or fade like traditional cardboard cards. They conveniently stack on top of the other Gray Fong accessory Domes for packing and come kitted with a Gary Fong lanyard for portability and accessibility.
