Testing two different illuminants
Applies two different light sources (illuminants) to a spectral measurement file and determines the amount of color shift that occurs.

Use this test to see what will happen if you view a measurement file under different light sources.

This test requires a measurement file that contains spectral measurements.

The measurement is opened in the worksheet twice using different illuminants. The Lab values are calculated using D50 (daylight) - and D65. The difference between them (in delta E) is calculated and shown.

Note: From this point, you can change the illuminant for either of these workflows by:
  • clicking on the list title,
  • choosing "Color Setup," and
  • choosing a new item under "illuminant"
This procedure can be used to
