PowerTracking
PowerTracking allows you to adjust your remote studio ash’s output power via the
camera’s FEC, ISO and aperture controls.
PowerTracking happens automatically when you have a MiniTT1 or FlexTT5 on
a Canon or Nikon camera and you are controlling a compatible studio ash with a
PowerST4 connected.
Center Point: The center point for PowerTracking is 3 stops down from your ash’s
maximum output power. All PowerTracking adjustments are based on this center point.
For example, if your ash’s maximum output power is 6.5, then the center point is 3.5.
PowerTracking with your camera’s controls: If there is no AC3 ZoneController on your transmitter, ash output
power on your remote studio ash will track up and down with FEC changes on your camera. Zero (0) on your
camera’s FEC control is the center point and equals 3 stops down from your ash’s maximum output setting.
Adjust FEC to raise or lower your ash power per the table on the previous page. See Camera FEC Range section
for more information.
Nikon: With no AC3 ZoneController on the transmitter, only the camera’s FEC control will
adjust ash power output level.
Canon: With no AC3 ZoneController on the transmitter, the camera’s ISO and FEC controls will
adjust ash power output level. The ISO in use for your rst picture will be used as the center point
for PowerTracking.
In the PocketWizard Utility for your transmitting ControlTL radio, this is called Full Manual and is the default operation
for PowerTracking when no AC3 ZoneController is in use. See below for settings in the PocketWizard Utility that allow
you to customize PowerTracking to also use your camera’s aperture controls for Canon and Nikon, or ISO controls
for Nikon.
