The Tiffen 4x5.65" Decamired Red Set of Glass Filters - Takes the guesswork out of determining color temperature. Acts as a conversion filter for color temperature adjustments from any point to any other point in the color temperature scale. Can be used to create "proper" coloration in unusual situations and to make creative alterations.

Applications include keeping color temperature constant during the course of the day and producing the effect of different times of day. Available in two series, reddish filters that warm the light and bluish filters that cool the light. Each series contains 4 densities: 1.5, 3, 6, and 12. Filters in the same series can be combined.

The decamired system has an advantage over the Kelvin system in that the Kelvin scale is not linear

Decamired readings provide more accurate/controllable readings than Kelvin

The difference between the Mired value of the film and the Mired value of the light is the Mired value of the correction filter that correctly tailors the light to the film
