General Canon Operational Considerations
Please consider the following operational considerations. These apply to all Canon cameras unless otherwise noted.
Calibration Shot
With a Canon camera and ControlTL radios the first exposure after initial connection or power-on is the calibration shot. This initiates communication between the camera and radio. This shot will not fire remote flashes. Always test-fire at least twice!
