Custom White Point dialog

The Custom White Point dialog is accessed by clicking the Edit.. button in the White Point section of the Edit

Calibration Target dialog.

A custom White Point can be created by either specifying it as a Black Body radiator temperature in Kelvin, as CIE (xy

chromaticity) Coordinates, or by taking a measurement.

Values between 2500K and 10000K may be entered in the Black Body K eld. The corresponding CIE xy coordinates

are automatically calculated and displayed for reference.

CIE xy chromaticity coordinates can be entered by selecting the CIE Coordinates radio button and entering the x and

y values. The corresponding correlated black body radiator temperature and Δuv (Delta-uv) values are automatically

calculated and displayed for reference. The Delta-uv value indicates how far the xy coordinates entered are from the

black body radiator locus.

A custom White Point may be measured using the calibration sensor, and automatically entered in the CIE xy chromaticity

coordinate elds by clicking the Measure button. This is useful for “cloning” the white point of another display monitor.
