How Illum Reader is working

Illum Reader is a function to analyse the light.

The purpose is to check the quality of your light into a viewing booths  or in yours viewing conditions.

This function can be usefull to check uniformity , the color temperature and the light into a booth.


This function need a spectrophotometer to work (XRite Eye One Pro 1/2, XRite ColorMunki Photo or an XRite I1 Studio)

How to use Illum Reader

Into the main windows of Coraye, click on the Illuminant pictogram (the third icon on the upper left).
