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.
