The Sekonic L-478DR provides triggering or flash control for the entire PocketWizard wireless family. Dynalite, Lumedyne, Photogenic, and Profoto incorporate the PocketWizard standard system. AlienBees, Einstein, Elinchrom, Canon, Nikon and White Lightning flashes connected to PocketWizard ControlTL products are perfect match to the L-478DR for power control.
The PocketWizard triggering systems use different frequencies in accordance with laws and regulations of the countries where they are marketed. Before purchasing a product using the PocketWizard system, be sure it is compatible with local regulations and the other PocketWizard products you use.
The L-478-series meters are especially useful when using flash to lighten shadows or reduce background detail. That’s because they measure ambient and flash simultaneously and automatically indicate the percentage of flash in the total exposure. Touch the screen to adjust settings to get the perfect the ambient flash mix. The meter’s analog display uses color-coded lines to graphically display the relationship between ambient and flash components.
Every camera system is unique. Optical, mechanical and imaging components all act on each other to produce slight differences in the dynamic range and exposure. Knowing the limits of your camera enables making better exposures with less post-processing.
Sekonic’s pioneering Data Transfer Software enables quick dynamic range mapping and meter calibration for the most precise control of light. Create and store up to ten profiles with Sekonic or X-Rite brand targets or use the touch display to directly enter profile information obtained from other sources.
Today’s digital cameras are boundless and a variety of cameras can be used in a single production. The L-478 series has two motion capture modes to fit camera in use. Touch to set shutter speeds for DSLR cameras in HD CINE mode or quickly select frame rates and shutter angles for cameras in CINE mode. Create unique frame rates and shutter angles for special effects.
Special effects and light sources can push standard camera settings to their limits That’s why the L-478 series also allows creating unique frame rates and shutter angles to .000 to enable precise exposure and lighting, producing the very best images and reduce time in postproduction.
Like all light and exposure meters, the L-478 series are calibrated for visual light. Because meters can’t measure filtered light by design, Sekonic designers added a unique Filter mode that enables getting exact light levels with touch screen ease. Touch the L-478 series to instantly call up lightsource or camera filtration expressed industry standard CTO/CTB/ND terms. For special filters or applications, create a unique filter factor and give it a name. Up to four filters can be used together as a pack to assure full control in virtually any situation.
Brightness measurement in Lux or FC and cd/m^2 or FL will make the L-478 series a major player on movie sets around the world. Display brightness along with exposure measurements or simply by itself.
The L-478 series’ contrast function simplifies setting up lighting ratios or checking the evenness of a background or scene. Take a reading of the key or reference light and touch AVE/EV to create a standard. Then press the measuring button to display the brightness difference between the standard and new reading.
Up to nine readings can be memorized. An indicator appears on the analog display each time a measurement is memorized. This provides a fast and simple way of retaining and analyzing shadow, mid tone and highlight exposure readings. Digital readings can be recalled and/or cleared at any time for precise exposure control.
The dynamic range of your digital camera or film can be programmed into the L-478 to create a Latitude Display that mirrors the range of your system.
Set a Mid.Tone from Tool Box to display the Latitude Scale. This important guide will let you know readings are within the range of your camera.
