DSC Labs Combi ColorBar/GrayScale DX-1 CG+4R Calibration Chart

The Combi ColorBar/GrayScale DX-1 CG+4R Calibration Chart from DSC Labs is a rear-lit chart designed for calibrating the color and resolution on your video camera. 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.

The name of this series refers to the "combination" of test elements. Each chart is a precision optical signal generator that produces waveform and vectorscope displays designed to mimic standard electronic test signals. It is designed for use with HD cameras, but can also be used in aligning older cameras using its included 4:3 framing bow ties. Multiple cameras can be aligned using the chart's color patches. The chart is also particularly useful when aligning different types of lighting, such as quartz, HMI, and fluorescent, among other light sources.

Each Combi chart is printed on a special substrate that is the result of a five-year research program. Benefits of this material include improved color stability, spectrophotometrically neutral grayscales (not possible with silver film), color pigments that complement real-life colors, and modern camera colorimetry.

This model features (6) vector colors and (4) skin-tone patches. It offers 11-step crossed grayscales, 100 IRE white, and (2) SuperWhites with true black chips. Hyperbolic resolution wedges up to 1200 TV LPPH (15MHz) are also included.
