 ☉ What is the working theory behind “RAYNAULD™ Directivity Color Calibration Filter”?

 

" RAYNAULD™ Directivity Color Calibration Filter" is the latest invention of camera external optical filter based on optical physics of shading, light guiding, filtering, restricted area light measurement, light focusing and diffusion in itself.

DCC Filter consists of a set of white cup-like filter installed within a retractable black barrel.  The filter cup is installed inside the black barrel. It can be used to adjust the illuminant level and color temperature value by adjusting the barrel length as well as the position of the filter cup in the barrel.

By adjusting the position of the opal filter cup within the barrel, the light is guided and illumination adjusted.  When the filter cup is extruded from the black barrel and exposed to the ambient light, the color temperature recorded by the camera gray card system is adjusted to capture “Visual Color” photographs.
