The Cambook-5 Grayscale Portable Chip Chart from DSC Labs is a grayscale calibration chart that can be used to calibrate virtually any video camera throughout the world. Many video professionals consider calibration charts a necessity for optimizing camera performance and the production value of images. This chart has been designed with that philosophy in mind and works equally well in engineering or production work.
Unlike most large calibration charts, the unit is small enough to fit in a briefcase or crate, ensuring that you have a calibration tool for mobile work and other projects that require travel or shooting outside of the studio. It features 5 different calibration charts, including crossed 11-step grayscale patterns, DSC CamWhite (true white), multibursts up to 800 TV LPPH, and DSC's unique backfocus star. All charts offer 16:9 and 4:3 framing.
