Light for photography is not only defined by its light intensity and luminance, but also by its color composition.

The Color-Pro 3F is specifically designed for measuring the photographic color temperature of flash and ambient light, and to indicate the measured results in degress Kelvin (K). However, there is much more to it. After comparing the color temperature measured with the pre-selected color temperature of the film, (in degrees Kelvin), the Color Pro 3F calculates the filter values required to achieve photographs without color casts.

The resulting filter values can be expressed as light balancing values in Mired or Kodak Wratten values. In addition, the Color-Pro 3F will indicate in CC filter values the correction required, for example, when working with florescent lighting.

Three of the most used film color temperatures are programmed into the meter (5500K, 3400K, and 3200K) but these can be freely overridden with color temperatures between 2000 and 9900K.

In addition, the Color-Pro 3F measures the intensity of the ambient light in Lux and of Flash light in Luxseconds.

• Color Temperature Range: 2000 to 40,000K
• Light Balancing Filters: -399 to 475 Mired scale. Switchable to corresponding Kodak Wratten filters.
• CC Filter Values: 0 to 95 Magenta and 0 to 95 Green.
• Light Intensity: 10 to 190,000 lux.
• Flash Power: 5 to 20,800 lux/seconds.
