Digital and Film Compatible
The PRODIGI COLOR C-500 and C-500R measures and displays color temperature and compensation values in LB/CC index or filter numbers for both digital and film cameras. In Digital mode, the color temperature and compensation readings are based on human visual response. In Film mode, readings are based on the color characteristics of traditional photographic film. By engineering the spectral characteristics of both systems into a single meter, Sekonic designers have given today's digital and film photographers greater control over lighting and color reproduction than ever before.
Wireless Radio Triggering Mode
(C-500R model only)
The PRODIGI COLOR C-500R is the first color meter to incorporate a flash triggering radio transmitter module. Simply press the measuring button to wirelessly trigger flash units up to 100 feet away. The built-in transmitter is compatible with PocketWizard's radio triggering systems, as well as the PocketWizard Wireless Freedom partners (Profoto, Dyna-lite, Photogenic, Norman and Lumedyne with built-in PocketWizard radio technology). The Wireless Radio Triggering Mode offers 32 digital coded channels and four Quad-Triggering Zones.

Illuminance Measurement
The brightness of continuous light sources is displayed in LUX (lx) or Foot-Candle (FC). Illuminance measurement is especially useful for cinematography, videography, theatrical and other applications that require precise control light source brightness.

Type: Three-color photographic color meter with four sensors to determine visual (digital) or photographic (film) color temperature of light sources and filtration required
Receptor head: Rotating (90Ao to the right/180Aoto left) receptor head containing four filtered photo diodes under flat incident light recepter

NOTE:
To comply with local broadcast regulations, Sekonic wireless systems sold in the various markets around the world are designed to operate at different frequencies. When purchasing and/or installing a transmitter module or using the meter with a receiver, be sure that the meter, module and receiver are designed to be used in your location and use the same frequency.
