Used Minolta Color Meter III-F

The Color Meter IIIf measures not only flash and ambient light, but also a mixture of the two. In addition to displaying the most suitable LB or CC filter number, this meter is equipped with color balance monitoring and measurement-correction functions, which allow you to control color reproduction with the utmost precision.

Consistently Accurate Color Reproduction

The Minolta Color Meter IIIf makes it much easier for photographers to maintain consistent color under various types of illumination. The meter measures the color of the light illuminating the subject and determines the filtration required to correct that illumination for the film in use.

The Color Meter IIIf can take measurements of both ambient light and flash. Ambient measurements are taken by positioning the meter and pressing the measuring button; measurements are possible under illumination levels from EV 3 to EV 16.3 at ISO 100. Flash readings can be taken in either cord or non-cord mode, with selectable shutter speeds from 1/500 to 1 second in full-stop increments. Measurements are possible for flash power levels corresponding to apertures (at the meter position) from f/2.8 to f/180 at ISO 100.

When measuring both ambient light and flash, selecting the Color Meter IIIf's analyze function will subtract the ambient light, and display only the measured results for flash light.

Measurements can be taken for any of the three major film types: Daylight (balanced to 5500K), Type-A Tungsten (balanced to 3400K), or Type-B Tungsten (balanced to 3200K). Measurement results can be displayed as LB (light-balancing) and CC (color-compensating) indexes, Kodak Wratten filter number and CC index, or photographic color temperature (determined color temperature based on film sensitivity). Direct display of Kodak Wratten filter numbers makes selecting filters very quick and convenient; if two Wratten filters are necessary, the Color Meter IIIf displays both numbers.

Color Meter IIIf users can store their own personal correction values for the recommended filtration. Correction values for LB and CC indexes can be stored in any of the meter's nine memory channels to custom-tune meter readings for the desired color reproduction. The correction values are added to the initial measured values to calculate the final displayed results.
