Designed to help digital photographers easily & efficiently achieve accurate, consistent colour results by providing quick reference points to balance colour & establish optimum lighting from the start of a photo session. Aimed at the professional & high-end prosumer photographers as well as professionals in the video cinematography & graphics arts markets. For the digital photographer in a studio environment, setting the correct ratio of main to fill lights & balancing the camera has long been an arduous back & forth process. Gretag Macbeth's new Color Checker three-step Grey Scale target is designed to make this process faster & easier by offering the photographer specific check points in a single target. Alternatively, when it is used under ambient light conditions as a reference in the first shot in a series, the photographer can quickly correct an image's colour by balancing on the mid tone grey value. The new Color Checker three-step Grey Scale target (white, 18% grey & black) provides reference values that can be checked & used to adjust colours within most common photo processing software packages
