Lighting Requirements

-   Light stability must be ensured to prevent color and/or density disuniformity during the scan.  Professional HMI lighting provide a perfect power stabilization in order to ensure always the same lighting conditions during the scan. Professional HMI lighting  are also  flicker-free to avoid interferences between the light and the CCD timing.   

-    A powerful and efficient lighting is recommended  in order to optimize the scan time and also the image quality.  In fact, to lighten correctly oversize subjects, a powerfull lighting system is obviously required. Furthermore more light cause the exposure times to be shorter and also allow using optimal optical settings.

Professional HMI light provide a very high power efficiency, UV radiation filtering to respect all curatorial concerns when acquiring artistic/ historical subjects and also a very low heating of the subject due to low IR radiations .

Metis has already tested several HMI lighting and selected the best products to be used with the DMC system. For further details on the "DMC Selected Lighting" or information about different lighting systems please contact METIS.
