Term
Read as "per mega Kelvin", this unit is based on the International System of
Units and is equivalent to the traditional unit of MIRED (mrd). It expresses
the inverse of the color temperature. The inverse of the color temperature is
1,000,000 divided by the color temperature.
Inverse color temperature = 1,000,000/Color temperature
The inverse color temperature decreases as the color temperature increases.

MK Ex.) 10,000K=100MK
If a 100K change is applied to both 10,000K and to 3,200K, the human eye
perceives the change applied to 3,200K as larger. In other words, there is a
difference in perception of the same change in color temperature depending on
the color temperature's numerical value.
When the inverse color temperature is used, the human eye perceives a given
amount of change as the same for any color temperature.

The difference of the reciprocal of the selected color temperature and the

Stands for Light Balancing ilter , and refers to a filter used for correcting color
temperature in photography. A blue filter is used to raise the light source color
LB Filter temperature, while an amber filter is used to lower it.
By using the custom settings in the C-700/C-700R, the display can be changed
to show the type of the filter brand being used.
