Lecture : 2/3/11 calibration devices-lightroom

The sensor in the calibration device can vary

1) colorimeter
measures 3 values RGB
reproduces what our eyes detect

Some spider devices can use more up to 7 sensors..more accurate information

subject to metamorism

2) spectro-photometre

measures light intensity  a whole lot of points along the spectrum red 700 ----> blue 400nm built up a complete curve

can counter the effects of metamorism
