Calibration...
2006-03-07 by Doug Lenos
The unit calibrates against the white/black areas
on the pad. Do the LEDs sensitivity to color, etc ever change? It seems like the
unit could be calibrated against an IT8 target similar to : http://www.adorama.com/IKKIT857.html
Just for my own understanding, anyone care to
explain why it only has to cal against B/W?
