RGB Data Capture |
Y. The VIVID 9i uses internal RGB capture. A three point lighting system was used to illuminate the object from the top and from both sides; this minimized shadows on the object. Each light in the system had 1-3 white light (5000k) flicker free fluorescent bulbs. The number of bulbs that were used to illuminate each artifact varied depending on ambient light conditions and object color. |
