☉ What is the “Absolute Color” of object? How to obtain it by photographing?
The “Absolute Color” is the true color of an image not affected by ambient light. Therefore, to shoot for an “Absolute Color” photo, the camera must be shielded from primary and secondary light sources so that only the intended shooting range is captured. To do so, fully extend the “Raynauld Directivity Color Calibration Filter” and hide the filter cup within the barrel (see illustration below), and make the “Manual White Balance” adjustment while pointing to the photographic scene. The “Absolute Color” of the photograph can then be captured. See the illustration below:
Of course, there are great differences between the “Absolute Color” and “Visual Colors”. The “Absolute Color” photos are faithful records of the colors of objects under various lighting conditions. It is useful for biological research, data records, medical researches, professional post-production color adjusting standards, and infant and child skin and health records comparisons, etc.
The setting of “Absolute Color Position” is most suitable for telephoto lens to shoot for long distance scenery or wild life with almost perfectly colored photo since the unnecessary colors and lights are reasonable blocked off.
