The Ambi-2 Illuminated Head from DSC Labs is designed as a replacement part or spare for the head that is included with the Ambi-2 Illuminator unit.
The Ambi-2 Illuminator system lets you customize camera set-up to shooting conditions by alternating between quartz, HMI, fluorescent, daylight and other illuminants. Used with different lamp types, Ambi provides test transparency illumination that is precisely color-matched to the types of lighting a camera will encounter. Setting up a camera's color matrix to several different illuminants, and then using the appropriate stored matrix setting during a shoot, can dramatically improve the visual quality and consistency of your images. Correct use of this system can allow you to achieve superior results, precisely matching colors to the type of lighting you are using in your setup.
