Calibrating projector

2009-02-03 by Nathan Gutman

Using Spyder2Pro. I wonder how the distance from projector to the screen affects the calibration. When calibrating the projector the screen to projector distance is limited by length of the Spyder cord which is about eight feet so there is a lots of light reaching the screen.
In actual use the projector to screen distance is much greater so consequently less light reaches the screen.
How does this affect the projector calibration?
Thanks,
