Sekonic’s pioneering DTS (Data Transfer Software) Version 3.0, introduced earlier this year, enables quick dynamic range mapping of both digital still and motion cameras for the most precise control of light and exposure. The automated process requires using the L-478’s 5-degree viewfinder and recording images of
one of Sekonic’s Exposure Profile Targets or one of ColorChecker® series targets by X-Rite®, all available as
a separate purchase. Measured data from industry-standard targets can also be manually entered in the software or meter. Up to ten camera profiles can be stored in the meter. Any number of profiles can be stored with the software. Once loaded, the Sekonic L-478 series can make incident and reflected light readings that are precisely tuned to the dynamic range of the profiled camera. A wide range of in-meter adjustment as well as complete exposure data input is also possible using the graphic interface of the L-478 series.

Exposure Profiling
Today’s DV cameras are boundless. The L-478 series meters have two motion-capture modes to fit the shooting needs of every cinematographer. Simply touch the screen to set shutter speeds for HD SLR cameras or quickly select frame rates and shutter angles for Cine shooting. They also allow users to create unique frame rates and shutter angles for special effects. Sekonic designers added a unique filter mode that enables getting exact light levels with the filtered light sources used in motion picture production. Simply touch the L-478 series to instantly call up light source or camera filtration expressed industry standard CTO/CTB/ND terms. Or users can create filter factors and names for precise control illumination and exposure. Extended ISO to 409,600 and brightness measurement in Lux/FC and Cd/m2/FL*2 will make the L-478 a major player on movie sets around the world.
