Sekonic C-700 & C-700R SpectroMaster Spectrometer Gives You Total Control of Color On Set

If you're trying to measure the color output of a light source, you're going to need a spectrometer like the Sekonic C-700 & C-700R SpectroMaster.

DISCLOSURE: This is a sponsored post by Sekonic.

You're probably familiar with light meters, which measure light output and display exposure settings for your camera. A spectrometer reads only the color of a light, and opens up a whole new world of control on set. If you're using different light sources while shooting, like Tungsten, LED, and HMI, and different brands within those sources, making them color match precisely can be a pain. You can take an educated guess with filters, but a spectrometer like the C-700 series will let you know exactly what color temperature your light source is, and then give you the filter you need to correct it, right down to the brand name and filter number.

Features

This is important for narrative work, but it can be especially important when you're dealing with visual effects or green screen, and you want to make sure you know what your light sources are doing. 

But that's not all. While Daylight and Tungsten are continuous light spectrum sources, other types of lighting, like LED and Fluorescent, can have gaps and spikes in their spectrum:

Using the C-700 & C-700R, you can measure the CRI (color rendering index) and special CRI of a given light source, telling you how closely a source accurately reproduces different colors. If you're wondering why things are a little off, or you're trying to compare different brands of technology, you can use the spectrometer to get an accurate reading and know precisely where your light source stands. 

Specifications

Check out a snippet of the C-700 Series specifications (the C-700R has wireless flash triggering):

  • Uses CMOS Sensor and Linear Variable Filter
  • Measures Flash, LED, HMI, Fluorescent, Plasma
  • Measures Tungsten, Natural Light
  • Reads Color Temp. from (1,600-40,000K)
  • Reads 0.09 to 18,600 fc (1-200,000 lux)
  • Large, 4.3" Color Touchscreen
  • Displays Color Spectrum Graph, CRI
  • Displays Rosco, Lee, Fuji, Wratten Filter Values
  • Multiple Light Comparison
  • 100' PocketWizard Triggering Range (C-700R only)
  • Price: $1,499 for C-700 & $1,699 for C-700R

Comparing Light Sources

The beauty of the C-700 series is how easily you can compare light sources. First, here's how single light sources are measured on the C-700/R:

And here's how it looks when you're comparing multiple light sources:

Software

The C-700 series also comes with handy software, which you can use to store different light sources for future reference, and even compare the same light over time to see how its color is changing with age:

With a spectrometer, you never have to guess what your lights are doing. The C-700 & C-700R SpectroMaster will help ensure that you can match any lights on set, and that there aren't any surprises once you get into post-production.

Great piece of tech. I'm hoping to get this or something similar soon.

I have their older Sekonic C-500 digital color meter, which I use at almost every shoot. It's very handy to know the exact color temperature of light when you're NOT shooting in RAW format. ( color mistakes are much harder to fix in non-raw formats )

I use the C-500 too, but I can't imagine shooting in any format w/out it.

People who use proper color / light meters - how far are apps like Cine Meter from these? I know they probably have far more features and are possibly a lot more accurate, but are there people who use something like Cine Meter in high end productions? And why wouldn't you?

Meters are scientific measuring devices calibrated w/in tight tolerances.
Apps use best guesses estimates based on broad support for whatever chips are supported by various OS iterations for use in a plethora of devices.

I own meters and have compared them w/ several Apps. Apps in some cases may be better then nothing; in worse cases they do more damage then good.

My own advice, buy a color meter if you are serious about cinematography.
A $50 analogue color meter is better then none (but won't work w/ CF or LED).

YMMV

The GOSSEN SIXTICOLOR color meter is one I used before I "upgrayedd" to to C-500. It uses Selenium for a chemical reaction to light, thus doesn't need batteries; however, the older the model the less accurate it becomes. It does strange things it you point it too close to a light source. It is known as whats called a blue/red meter and works well for daylight or tungsten. It doesn't read Florescent/LED/green light correctly. Try one out before you buy if you can. They are using $30 to $70 on ebay, but can also be scored from KEH, B7H used dept, and misc film camera shops.
