Pocket Wizard AC3 ZoneController Guia De Inicio Rapido página 5

The AC3 ZoneController enhances the ControlTL capabilities
of your MiniTT1 and FlexTT5 radios by allowing you to
control the flash output power manually from the camera's
position or use i-TTL.
AC3 Manual Mode: The Power Dial sets the remote
Speedlight power output as shown in the table on the right.
AC3 Auto Mode: The Power Dial sets the Flash Exposure
Compensation (FEC) relative to the i-TTL exposure for that zone.
Manual and Auto modes can be used at same time. Manual
zones will not be calculated as part of the i-TTL exposure.
Zones set to 0 / (OFF) will not trigger.
FEC NOTE: In Auto Mode, Flash Exposure Compensation
(FEC) can be set in more than one place and the values are used
together - all positive and negative FEC values will be combined.
FEC can be set:
• On each zone independently using the AC3 Power Dial
when the zone is set to A (Auto)
• On each remote Speedlight
• Using the camera's FEC control. All AC3 zones set to
A (Auto) will be affected equally.
If the combined FEC adjustments are more or less than your
flash's capabilities, then the flash will operate at maximum
or minimum output accordingly.
* The Power Dial can adjust over a 6 stop range. To achieve the lowest manual power settings
on your Nikon Speedlight, like 1/128, you'll need to adjust FEC down accordingly.
