PowerTracking Tab
PowerTracking Control: Adjusts how ControlTL-capable remote studio flashes, like flashes connected to a
PowerMC2, respond to the AC3 ZoneController in Auto Mode, or to a ControlTL Transmitter with no AC3. See the
ControlTL & PowerTracking section for information.
Full Manual (default): Turns off PowerTracking for aperture and ISO. See the Basic Power Control section
for more information.
Nikon: With no AC3 ZoneController on the transmitter, only the camera’s FEC/EC control will adjust flash
power output level.
Canon: With no AC3 ZoneController on the transmitter, the camera’s ISO and FEC controls will adjust flash
power output level.
With an AC3 ZoneController on the transmitter, any zones set to Auto Mode will operate as Center on ISO
& Aperture with First Shot (see below) when this control is set to Full Manual. AC3 Manual Mode
can be used to adjust flash output power manually with an AC3.
Center on ISO & Aperture with First Shot: Aperture and ISO as set on the camera for the first exposure
will be aligned with the ControlTL center point (3 stops down from your flash’s maximum output power). For
example if your camera is set to ISO 100 and F:5.6 for its first exposure, then those exposure settings will yield
a flash output power of 1/8. Adjustments to aperture, ISO, and FEC will adjust flash output power accordingly,
as will adjusting the Power Dial on AC3 zone in Auto Mode. See the Automatic PowerTracking section
for more information.
Center on ISO & Aperture: Lets you set the aperture and ISO that will be aligned with the ControlTL center
point (3 stops down from your flash’s maximum output power). Adjust the drop-down boxes for the Aperture
Center-On and ISO Center-On values you want to use.
