There are still many types of photographic equipment that can scare all but the very experienced, and certainly colour temperature meters come under that description.

I am always pleased to help shed some light on their use, as they can play a fundamental role in high level photography.

There are now two new Spectromaster models from Sekonic. They look interesting as they can deal with ‘difficult’ light sources and their colour characteristics including LED and Fluorescent lighting.

And if you want to understand how to measure and control colour with clear step – by step guidance, please have a look at our ‘Understanding Colour Crash Course’ seminar. (Click Here).

Here we go with the official information from the distributors:


JP Distribution is pleased to announce the new SPECTROMASTER C-700 and C-700R spectrometers by Sekonic.

The new SPECTROMASTER C-700 series are the first spectrometers that measure every light source (LED, HMI, Fluorescent and the natural light spectrum) PLUS wireless Flash (C-700R only compatible with PocketWizard© wireless system). In addition, with it’s CMOS linear image sensor, the SPECTROMASTER C-700 series make it possible to measure in 1 nanometre (nm) increments, capturing spikes in light source output, especially LED’s and fluorescent, providing unmatched colour measurement accuracy.

Through it’s sophisticated CMOS sensor and advanced software, a wide range of colour temperature readings can be measured from 1,600 to 40,000 Kelvin (K). With it’s intuitive large (4.3” colour dot matrix LCD) colour touch screen, the SPECTROMASTER C-700 series offers easy navigation through spectral distribution screens, lighting comparisons, Colour Rendering Index (CRI) colour data and much more. It is also the first spectrometer to measure wireless flash providing colour and light output data. Flash units can be triggered up to 30 meters (100 feet) or more using the PocketWizard wireless triggering system. Any flash can be triggered and measured with a touch of the meter’s measuring button.

C-700R Hero_LCDchange-clrbckgrnd•Measures LED, HMI, Fluorescent, Tungsten, Natural Light and Flash in 1 nanometre (nm) output wavelength increments from 380 to 780nm.

•The world’s first stand-alone spectrometer that measure the flash light with wireless Triggering with a PocketWizard© Receiver Attached (C-700R Only).

•Wide measurement range of Colour Temperature (1,600 to 40,000K) and illumination (1 to 200,000lx in ambient light, 20 to 20,480lx/s in flash light) in both Digital and Film Mode.

•User-friendly design: 270 degrees swivel head, dark calibration without cap, large 4.3” colour touch panel LCD and Customise function.

•Various displays (Spectrum Graph, CRI, Text, Lighting Filter for Rosco© and LEE©, Camera Filter for Kodak Wratten©, LEE© and Fuji©, White Balance Compensation, Multiple Lights Comparison Modes).

•Measurements of Kelvin (K), Illuminance (lux), LB/CC Filters (for Camera Lens or Lighting Filters), LB/CC Index, CRI (Ra, R1 thru. R15), ⊿uv.

•Up to 99 data can be stored in memory.

•C-700 Series Utility (in CD-ROM included in the package) offers easy settings in the meter and analysis of memorised data in computer.
