Color Temperature Nomograph
The color temperature nomograph is used to compute the necessary Kodak color balancing and/or correction filter(s) to convert a light source from one color temperature to another. Instructions for operation of the tutorial appear below the applet window.
The original and converted source scales each have a movable arrow that is connected by a straight line. To determine a color temperature conversion or balancing filter value, use the mouse to move the arrow on the left-hand scale (original light source) to the color temperature of the current microscope light source. Next, move the arrow on the right-hand scale to the desired color temperature adjustment. As the arrows are moved, the straight line connecting them will also be translated across the center scale. When the arrows are correctly positioned, the connecting line will cross the center scale at the point where the appropriate filter lies. This filter value (the actual Kodak filter number) will be displayed at the bottom of the applet window.
