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.
There are three different display mode options.
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.
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.
The photographic color temperature of the light source is measured in degrees Kelvin and determined according to the spectral sensitivity of color films.
Film and lighting equipment manufacturers all claim that their products are balanced to “daylight” (5500K) or “tungsten” (3400K or 3200K). However, their testing is performed in laboratories under highly controlled conditions. We live and photograph in the real word. CCD and CMOS sensors from different manufactures read and interpret color differently. Film from different manufacturers render color differently. Different batches of the same film render color differently. Different lighting equipment renders color differently. The quality and age of that equipment is also a factor. The sun cannot even be relied upon, rarely shines at a perfect (5500K) and can vary widely depending on time of day, weather and pollution in the air.
The KCM-3100s nine memory channels make coping with these challenges much more simple. Once you determine the correct filt ration for the film or equipment being used you can simply enter the difference between your filt ration and the meter reading into the meter’s memory. The meter will adjust all future reading accordingly.
A selectable range of shutter speeds from 1 full second down to a fast 1/500 of a second set in full stops for flash measurement. Lighting for Flash photography usually is made up of a combination of flash and ambient light. The KCM-3100 measures the "mixed" lighting at the selected shutter speed. After measurement the shutter speed set in the meter can be changed which effectively changes the ratio of ambient light to flash. The meter will automatically recalculate the results and display the new reading for the new shutter speed.
