Kenko Tokina Co., Ltd. Light Meter

One of most important value for Photograph is exposure.
Kenko light meter can select best exposure value


 
 
Kenko KCM-3100
 
 

Three Display Modes 

LB (Light Balancing) and CC (Color Compensating) Indexes 
The LB index is used to select the right amber or blue LB filter needed to balance a light source. Its measurement is the mired difference between the photographic color temperature specified for the selected film type and the temperature of the light source. The CC index is the value of the required magenta or green colored CC filter. 

Filter number and CC index 
The Kodak Wrattan light balancing filter number (or numbers) needed, display directly in the LCD to make easy selection of amber or blue LB filter (s). The CC index is the value of the required magenta or green colored CC filter. 

Photographic Color Temperature 
The photographic color temperature of the light source is measured in degrees Kelvin and determined according to the spectral sensitivity of color films.

Kenko KCM-3100 Color Meter

Knowing the color temperature before taking a photograph saves you time and money

Ambient Light Readings 
First set the appropriate film type, choose the display mode and memory channel (if present). Set the Mode switch to "AMBI", then simply aim the meter’s light receptor at the scene and press the measurement button.

Measurement readings will be calculated and appear in the almost immediately and color temperature measurements will be taken as long as the measurement button is held down. The KCM-3100’s measuring range for ambient light is EV 3 to 16.3 using ISO 100.

Kenko KFM-2200 FLASH METER

Light Meter For Both Flash and Ambient Meter With Integrated Spot Meter. Include ISO variable mode

Kenko KFM-2200
  • The integrated exposure meter combines incident light measurement and spot (reflected light) measurement in a single unit.
  • The Flash Meter KFM-2200 is designed to be used with both digital and film cameras. It provides unique method for measuring the light when using with digital cameras.
  • Using Display function. required values can be measured for 3 parameters selected: FNo, shutter speed or ISO. To measure the required value for one parameter just input data for two of other parameters using the up/down dial to input the data.
  • New measurement display window has a back light to read the measurement results easily evevn if it is used in a darkened environment.
  • When used with the flat diffuser, KFM-2200 can work as simplified Lux meter.
  • For spot measurement. the Flash Meter KFM-2200 uses a parallax-free optical system. This eliminates the displacement of the measurement area that varies with the distance from the subject.

Flash Light Reading
When using with flash, select Cord or Non-Cord depending on the shooting conditions. For Cord setting, connect the Flash sync-cord to the Sync Terminal in the front of the KFM-1100 then a light reading can be taken by simply pressing the Measurement button on the side of the meter. When using a non-cord set-up, pressing the measurement button sets the meter in stand-by mode. When the flash is fired manually, the meter takes a reading.


Analyze Function 
When taking readings in mixed flash and ambient lighting, the KFM-1100 can measure the flash and ambient light almost simultaneously. The percentage of flash light in the over-all exposure is then displayed in the analyze scale on the LCD. The analyze scale is divided into 4 sections, each section represents flash contribution of approximately 25% of the total lighting. For example, if 3 sections of the analyze scale are lit, the flash to ambient light ratio is approx. 75% flash to 25% ambient. After taking a reading, the shutter speed can be changed and the meter will recalculate the exposure. Setting a slower shutter speed would result in a greater ambient to flash ratio. Setting a faster shutter speed would result in a lesser ambient to flash ratio. The analyze scale helps you balance the 2 sources of lighting for more predictable results, so you can set the lighting and exposure to get the look you want.


Calculation Function 
The KFM-1100s calculation function can be used to average readings stored in memory or bias exposures toward shadow or highlights when taking reflected light readings. This allows for more accurate recording of shadow or highlight detail.


Memory
 
The KFM-1100 has memory slots to store 2 separate readings. Both stored readings and the current reading are displayed simultaneously in the analog scale. Memory markers also show the number of stored readings. Having readings stored in memory makes it easier to analyze the contrast range of your subject, the lighting ratio or viewing several separate readings in relation to one another.

LIGHT METER For Both Flash and Ambient Light Readings - Simple, Easy-to-Use, Accurate

Ambient Light Readings
The KFM-1100 shutter speed can be selected in a range from as long as 30 minutes to as fast at 1/8000 of a second (This range is selectable in full stop, _ stop or 1/3 stop increments). The light reading is displayed on the meter’s LCD window as both digital and analog data. If you wish to select a different shutter speed after a reading is taken, the aperture reading will automatically change accordingly. The KFM-1100 can read a very wide range of light from the very low equivalent EV -2.0 to EV 19.9 (incident light based on ISO 100). The meter can also be set to a Cine mode to be used with Cine cameras and display light readings from 8 to 128 frames/sec.
