Color Temperature

Consistent and Constant

The problem: With the rare exception of units costing many thousands of dollars, flash lighting packs, up to now, do not control the color temperature of the light. The color temperature typically decreases by over 100 degrees Kelvin for every f-stop of power reduction. Over a 6-stop adjustment range, this results in a color temperature decrease of over 600K. Even units that have a small 3- stop range can produce significant color shifts of over 300 degrees. This can result in much larger shifts between two light sources than film can correct. (Kodak recommends less than 200 degrees shift between light sources for their 5500-degree daylight film.)

The solution: Photogenic has created an affordable solution to this problem. The new StudioMax III’s provides consistent and constant color temperature across their 6-stop range. Be wary of claims of consistent color temperature at only one power level. This is not the same as constant-colortemperature over all power levels. Both are necessary to provide the perfect exposure we all strive for. The light produced by the new AKC’s is consistent & constant. Every time you set a desired power level, you will receive the same amount of light as you obtained previously, and at the same color temperature. The light produced by the new StudioMax III is constant-color. No matter what power setting you select, the light will be the same color temperature. Using the standard color corrected flash lamp; every subject will be exposed to approximately 5400 degree Kelvin light, regardless of power setting. This solves forever the problem of unbalanced power settings in your studio, resulting in color temperature shifts in your pictures.

Reciprocity Explained

-Excerpts taken from Kodak TECHNICAL PUBLICATION DATA I FILM E31- July 2002

The reciprocity law states that the intensity of light falling on a photographic film multiplied by the exposure time equals the total amount of exposure.

Intensity x Time = Exposure

This means, for example, that an exposure of f 16 at 1/60 second is equivalent to an exposure of f 11 at 1/125 second. In either combination of settings, the same total amount of light reaches the
