Combis are easier to use . . .

. . . because they are precision "Optical Signal Generators" (OSGs) that produce waveform and vectorscope displays designed to mimic standard electronic test signals. Featuring a "Combi"nation of test elements, Combis save time and are easier on the budget.

Designed for HD, but Combis can also be used in aligning older cameras using the include 4:3 framing "bowties". When recorded to tape or film, Combis provide the ultimate on-scene-reference for optimizing image quality in post.

Customizing a state-of-the-art electronic printing process Combi-DX1 charts are the result of a five year DSC research program to develop the ultimate test materials. Combi DX1 benefits include:

Improved color stability
Spectrophotometrically neutral grayscales - not possible with silver image film
Selected color pigments with spectral characteristics that complement real life colors, and modern camera colorimetry
Greater flexibility enabling more different patterns
DX-1 patterns match CamAlign front-lit chart colorimetry.

Combi-DX1 takes the guesswork out of matching video cameras!
Align multiple cameras using Combi-1's color patches and you will be delighted how simple image matching can be. Combi-1 is especially helpful when aligning to different types of lighting, quartz, HMI, fluorescent etc. Our aim is to give you consistent, virtually identical outputs - every time! Combi deviation from aim values are specified in CIE units. Maximum tolerance for any color is 5 CIE L*U*V units, with an RMS maximum of 2 units. As a yardstick, cameras considered "well matched" by eye, typically have a CIE color difference of 10 units.

Choose the Combi-1 that's Best for You!
Standard models are 4:3 format and measure 8x10" OD. 16:9 HD versions include 4:3 framing "bowties" for SD use and are 8x13.5" OD

To avoid moiré and other problems caused when typical printed patterns "beat" with a camera's CCDs, all Combi-1 and Combi-2 OSGs are produced on continuous tone or dye image films. Mounted in shatter-proof, clearer than glass plastic, OSGs are packaged with individual calibration sheets in sturdy protective cases.

Uncertain which camera to buy? Combi-DX1 can be invaluable in helping you make the best purchase decision, with confidence.

Use with other Illuminators
While Combis are designed to be used with the Ambi illuminator we can supply CombiMattes to use Combi OSGs with other manufacturers' light boxes or spherical illuminators.

Other OSGs

72-dB 13-Step Greyscale
Ideally suited to "electronic cinematography", this 13-step true log pattern, with its more than 3000:1 dynamic range, demonstrates a camera's performance from white to the darkest shadows and jet black.

Ask about the many other specialized patterns such as flare, HD monitor registration, etc. If we do not have the exact pattern you need we will be pleased to discuss custom patterns.

DSC test products are covered by one or more patents: US4779136 and 5850256 - with other patents pending.
