Kenko KCM-3100 Overview

The Kenko (THK Photo Products) KCM-3100 Professional Color Meter reads both ambient and flash light. In photography, accuracy is what counts. When shooting in any kind of mixed lighting scenario, a good, reliable color meter is the only true and proven way to get accurate readings. In areas such as commercial, fashion and certainly architectural work, a color meter is a "must".

This meter is designed with a minimum of clutter and is very user-friendly. The large LCD readout combined with its variety of features make this meter a top contender.

The KCM-3100 has 3 display modes for displaying color temperature. Each mode is designed for a certain type of photography or filtering system. LB (Light Balancing) index is used to select the necessary amber or blue LB filter; The Mired difference between the specific photographic color temperature for the selected film type and the light source.

CC (Color-Correction) displays the Kodak filter number(s) of the necessary light-balancing filter(s) to make for easy selection of the required light balancing filter. Whereas the LB system uses amber or blue filters, the CC system uses magenta or green color compensating filters.

Finally, it displays color temperature in degrees Kelvin. This is a useful setting to determine filtration based on the light source and the spectral sensitivity of the film used.

Other benefits of this meter are its ability to read in either sync or non-sync mode, i.e. without a cord. It also has an "Analyzer Mode" for measurement of flash lighting only. Setting the shutter speed to "F", the meter will only read light from flash.

Finally, The KCM-3100 has 9 memory channels which can be custom set to specific lighting situations or individual film characteristics. By doing this, you can be pre-set for certain types of film or lighting set-ups.

Commercial production moves pretty fast at times. Having the Kenko temp meter helps keep me honest in delivering even light balance when needed. The only thing I would change is to put the tables in the LCD and not on the back. All you would need is a selection button. To get really fancy the LCD could be in color and to give you two color samples, previous and corrected. Please pass along to Kenko. Thanks

performs better than expected...

I purchased the KCM-3100 to use with both film and digital. The first thing I noticed with digital is that the color temperature is different from my dSLR (Canon 5DII) by about 200 K depending on the situation. The dSLR has the as shot K value in the RAW exif data including RGGB data and 'correction' ratios for various color temperatures... Using the KCM-3100 with the dSLR has helped me understand the LB/CC digital process. With film (mostly shooting Fuji PRO400H) the meter performs as expected. The item costs about 2x as much in the local (Japan) market... international delivery was quick (ordered on my Tuesday, delivered on my Friday

A must for arena strobe shooting

I use my Kenko meter for sports photography in arenas. Tired of the color temp of your backgrounds not matching the color temp of the close-up subject? The light fixtures in most arenas have two colors of non-daylight-colored light. Like most non-incandescent lights, they pulse many times per second -- one dominant color and a second that emits as the power falls off before the next pulse. Although easy enough to look up the specs on the bulb/fixture manufacturer's web page, it's often impossible to determine the precise type of bulb used in your locations fixtures, and in any event the wall paint schemes affect the hue. This meter helps me measure the two temps of the ambient lighting, and then gel my arena strobes first to absorb the primary hue missing from the ambient fixtures, and then to gel again to absorb the second hue. The meter is then used again to fire the strobes, and then by changing the shutter speed on the meter with that single reading, it reports both the color of the strobes and the ambient light to help ensure you've got them reasonably matched. It's expensive, but if you invest the time to master it, you can build formulas and gel packs for every arena you shoot. I've even used it on occasion to gel my camera-mounted strobe to match the ambient light.

When they say ambient , will it take both incident and reflective light or just incident?
Asked by: Troy G.
I think they mean it doesn't measure flash.

how reliable is this colormeter with led lights ...

how reliable is this colormeter with led lights and hmi?
Asked by: Antonio
Although this meter is suitable for reading the color of an HMI lamp, it is not optimized for LED lighting. A better option for both would be the Sekonic C-800 SpectroMaster Color Meter, BH# SEC800SM

Can this also give a light intensity reading (such as footcandles or lux)?
Asked by: Kenneth H.
No, the 3100 color meter does not give light intensity readings in either footcandles or Lux.
