KELVIN<br />

Kelvin 351<br />

•<br />

Description<br />

Degrees Kelvin is the standard unit of measure for color temperature which is<br />

a way to characterize the spectral properties of a light source. Low color<br />

temperature implies warmer (redder) light, while high color temperature implies<br />

a colder (bluer) light. Presets for a number of different light sources and<br />

conditions are provided in degrees Kelvin.<br />

Color Temperature<br />

The Color Temperature of the image is determined by the difference of the<br />

Destination and Source Kelvin parameters. For instance, if your Source Kelvin<br />

is 3200 degrees Kelvin and you adjust the Destination Kelvin to 6500 degrees,<br />

your image would turn blue. This is the same as using tungsten indoor film<br />

meant to be used with lighting balanced for 3200 degrees Kelvin outside in<br />

daylight which is 6500 degrees Kelvin.<br />
