Product Overview

The Sekonic SpectroMaster C-700 is designed for motion and still Image capturers who must produce quality results with proper subject color while working with multiple types and brands of light sources. A full-spectrum Color Meters the C-700 can precisely measure LED HMI and Fluorescent as well as tungsten natural light and electronic flash. The C-700s' large color touch screen displays light-source color spectrum and CRI for multiple sources plus Kelvin (correlated color temperature) Illuminance (footcandle or Lux) and light source filtration values in Mired CC as well as filter correction values for major light source and lens filter brands. Its high-resolution measuring system featuring CMOS sensor enables capturing spikes in light source output to provide unsurpassed color measurement accuracy. Different than any spectrometer today the C-700 meters not only displays more light-source information it also provides filtration information to correct and modify light color for cleaner recording and simpler post process.
