Gossen Color-Pro 3F Color Temperature Light Meter

Gossen Color-Pro 3F

Gossen Color-Pro 3F Light Meter

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. The resulting filter values can be expressed as light balancing values in Mired or Kodak WrattenTM 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.

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.  

Measures Ambient Light and Flash Light Intensity,

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.

Calculates Filter Values

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 WrattenTM 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.

Filters can be displayed as mired values or as Kodak Wratten types. For fluorescent light, the required color compensating filters are indicated as CC values.
