Intended for photographers, videographers, cinematographers, and gaffers, the C-800 SpectroMaster Color Meter from Sekonic is an advanced field meter capable of reading virtually all light sources whether they're LED, flash, incandescent, HMI, fluorescent, or in the natural light spectrum. Most importantly, it's a practical lighting tool that analyzes the light source using 11 different display modes on its 4.3" color touchscreen, indicating specifically what you need to do to achieve your desired effect. The meter's CMOS sensor enables measurement in increments as fine as 1nm and allows capture of color spikes in the light output - an especially valuable function when working with LED, HMI, fluorescent lighting, and mixed sources.

Perhaps the meter's most exciting addition is Spectral Similarity Index. Developed by the Sci-Tech Council of the Academy, SSI gives the user the ability to set any light as a standard, or use predefined standards (such as CIE D55), and then gives other lights an SSI score based upon how well they will match. The C-800 also includes TLCI (Television Lighting Consistency Index), TLMF (Television Lighting Matching Factor), and TM-30-15 (Technical Memorandum) in addition to CRI (Color Rendering Index), which can be measured singularly or in two light comparison mode.

The SpectroMaster has very impressive accuracy, repeatability, and response specs and a wide range of values in all modes. Flash for example, can be color analyzed with selectable shutter speeds from 1-1/500 sec. Ambient light has a 1.0 to 200,000 lux range (0.09 to 18,600 fc). The intuitive color touchscreen offers access to the meter's many functions including a Spectrum graph, CRI, Camera Filter, Lighting Filter, White Balance Compensation, and comparison of multiple lights.

The Text mode screen displays color temperature, lux or fc as well as color compensation and light balancing filters. After selecting your preferred color balance, the Camera Filter and Lighting Filter Screens will display the actual Rosco, Lee, Kodak Wratten, or Fuji filter designations necessary to achieve your targeted color temperature. CRI also has a dedicated screen that displays standard color reference values (including R1 thru 15) as a percentage of the light source's ability to reproduce a color accurately, as compared to the Ra standard temperature. The Multi Light Screen reads multiple light sources' color temperatures as well as light balance and color compensation recommendations, memorizes them, and allows them to be compared.

With its plethora of light-analytic tools, ability to read and compare all types of light and real-world filter solutions, the SpectroMaster is destined to be a staple on set.

CRI, TLCI, TLMF, TM-30-15, and SSI

Developed by the Sci-Tech Council of the Academy, SSI (Spectral Similarity Index) gives the user the ability to set any light as a standard, or use predefined standards (such as CIE D55), and then gives other lights an SSI score based upon how well they will match. The C-800 also includes TLCI (Television Lighting Consistency Index), TLMF (Television Lighting Matching Factor), and TM-30-15 (Technical Memorandum), in addition to CRI (Color Rendering Index) which can be measured singularly or in two light comparison mode.

Match Light Sources by Measuring x, y and Hue Saturation

The C-800 has more color control parameters specifically designed to help match lights to one another. CIE1931 (x, y) has been added, giving users the ability to measure and dial-in specific chromaticity coordinates into lights of some major brands. Hue and Saturation units of measure have also been added to better match RGB LEDs to any light source. In addition, new display screens provide easy interpretation and understanding of the new data fields, making this a superior meter for all applications.

Designed to be Used on Set

  • Fast button layout for single-handed operation
  • 270° Swivel head to measure from any angle
  • Built-in dark slide for effortless on-set use
  • Measure Virtually any Kind of Light

    The C-800 series incorporates a CMOS linear sensor, that measures and evaluates the true color temperature of a light source from 380 to 780nm in 1nm output wavelength increments, capturing spikes in output of conventional light sources as well as fluorescent, flash, HMI, and LED sources.

    Measurements

    Measurements include Kelvin (K), Illuminance (lux/fc), LB/CC filters (for camera lens or lighting filters), LB/CC Index, CRI (Ra, R1 thru. R15), ⊿uv, SSI, TLCI, TM-30-15 (Rf, Rg), CIE1931 (x, y) chromaticity coordinates, Hue, Saturation.

    Expanded Color Rendering Properties

    Standards include CRI, SSI, TLCI, TLMF, and TM-30-15.

    Sekonic C-800 Reviews

    Its fine.

    Feature wise - this is an amazing meter - I love the snapshot comparison option when dialing in colour - especially when it comes to matching RGB / CMY lights. However (and I knew this before purchasing, but refused to believe it..) Its slow. In low light environments (10-30fc) its slow... sometime - painfully slow... I tend to use it now for initial fixture line up and it sits beside my console and use my old Minolta for on set references... Would I buy it again - yes. Would I recommend it.... With the above stated caveat, yes.

    Everything for color accuracy is in this beautifully made instrument. It is expensive but well worth the money for solving color variants that are not readily apparent.

    Great meter if you want to get very precise with your lighting! When I Shoot interviews I like to match the color temperature of the room to avoid having to correct it later in grading. Being able to meter it exactly has not only improved my results but helped me get the proper lighting much more quickly! I would absolutely recommend this to anyone looking to improve their lighting game!

    Gosh, for the price, the touch screen is so hard to make work. I called sekonic and they confirmed that it is tough to make react. Frustrating. I have 2 other sekonic touchscreen light meters and they are perfect! Bummed about this one. Returned, unfortunately.

    Wish they would just have another dome on the other side and used it as a light meter function. Why carry two things when you can carry one!

    This is not your average color meter. If you're working in environments with mixed lighting where color accuracy is a must, this is your instrument. Buy it while you can!

    Asked by: Alejandro
    This color meter can give you exact information based on the color of the light. Depending on where and how you meter relative to other lights you can get a combined reading or a reading per light. Color meters are more accurate than gray cards for setting white balance.

    What are the main differences between this one and the C-700-U? Also does C-800 give you F-stop values like a lightmeter? Or should I get a different light meter for that purpose?
    Asked by: Ege
    This is a color meter. While it can measure illumination levels in lux and footcandles, it does not measure in f/stops, shutter, ISO etc, etc. You do need a light meter for that. The main difference from the 700 is that the 800 can measure more types of light. In particular, it is the only affordable, movie technician meter that can measure the new color standard, Spectral Similarity Index (SSI) which is more reliable than CRI.
