Our eye is a fantastic adaptive bio-device that works very well for comparison and can adjust itself to most of the watching conditions: in fact, we have the strong impression to be able to judge the whiteness of marble with the direct sunlight as well as in a not-too-well illuminated closed space or with bad weather.
When it comes to deliver accurate colorimetric information with the support of pictures, the task seems hard: the trend is to capture the color of a (supposedly) well-known object along with the marble surface, which already may somehow help to a certain extend. Capturing correctly (colorimetric faithful images) a whole natural stone block implements a lot of knowledge and technology to grant that whatever the weather and the outdoor lighting conditions, pictures taken at a different time of the day or year and in different conditions may return the same result in the term of color definition.
That is the primary aim of any Capturing Station (CINEMA STUDIO fix Station or EISENHOWER mobile station), to recreate a perfect dark ambiance where a calibrated illumination may give to the natural stone color the accurate image definition. Another task is to easily manipulate the block to turn and tilt it in front of the Capturing Device.
That is possible thanks to the combined action of 3D SWINGER (intelligent Roto-translator) and 3D TANGO (Smart Tilter), which can together orientate in the space the block so that all its sides are captured, and their color and shape will be perfectly suitable for any following onward elaboration. To grant that the shooting process has been correctly pursued, the Marmo3D system provides a set up of colorimetric charts that can be measured by the software, checking that all colorimetric parameters are falling within given strict tolerances.
