Gossen Color-Pro 3F Color Temperature Light Mete

The safe way to perfect color photographs and the true reproduction of the color:

Light for photography is not only defined by its light intensity and luminance, but also by its color composition. The Gossen Color-Pro 3F is specifically designed for measuring the photographic color temperature of flash and ambient light, and to indicate the measured results in degrees 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 out the filter values required to achieve photographs without color casts.

Gossen Color-Pro 3F Light Meter Key Features

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

And still another useful capability: the Color-Pro 3F measures the intensity of the ambient light in Lux and of Flash light in Luxseconds.

Ergonomic Design

The button for measuring the light is conveniently placed on the right side of the meter, as are the buttons for changing the values up or down. Buttons for changing the functions left or right are on the front of the meter.

After comparing the color temperature measured with the pre-selected color temperature of the film, in degrees Kelvin, the Color-Pro 3F calculates out 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^TM values. In addition to the above the Color-Pro 3F will also indicate in CC filter values the correction required, for example when working with fluorescent lighting.
