Q: How do I use the White Reference?

Using an image with a white area in it, select the CIE XYZ color space. Create a region of interest that only includes the white part of the image. Record the average X, Y, and Z values. Then switch to the CIE L*a*b* color space and use the previously recorded X,Y, and Z values as the White Reference.

Q: Reposition Region of Interest and Reference Coordinate System are dimmed. How can I make these options available?

Insert a Set Coordinate System step before this step to make the Reposition Region of Interest and Reference Coordinate System controls available.
