AUTOMATED FOLLOWSPOT CALIBRATION
If the light that you are defining will be used as an automated followspot, you need to
do a followspot calibration. The MLD needs to know the exact position and orientation
of the light that you want to convert into a followspot. You may enter this information
manually, but this can be a tedious procedure, particularly if your fixture is difficult to
reach or if you have several fixtures to measure. Consequently, an automatic calibration
routine has been implemented for your convenience.

1. AUTOMATIC CALIBRATION
The automatic calibration method involves pointing the lights to four points on the
stage floor, called “lighting calibration points”, and then measuring those points with the
tracking system.
a) Define the four lighting calibration points. You have two options:
Either i) you can use the four calibration points that you marked during speaker
calibration. Using these stage marks has the advantage that you have already
measured their position with the tracking system. If you use these marks
remember that the numbering is as follows:
