PocketWizard PowerMC2 Quick Manual - Automatic Powertracking
Automatic PowerTracking
When Automatic PowerTracking is engaged, any changes to aperture and ISO on your camera are automatically
tracked by your remote flash output power to maintain the current exposure level. For example, if you open the aperture
on your camera by one stop, then the power output level on your remote flash will decrease by one stop.
To engage Automatic PowerTracking when you are not using an AC3 ZoneController, set the PowerTracking mode to
a setting other than Full Manual. This is done in the PocketWizard Utility for your transmitting ControlTL radio only.
PowerTracking has several modes of operation available. See the PocketWizard Utility section on adjusting this setting
via the PowerTracking Tab for more information.
The following directions are for the PowerTracking mode Center on ISO & Aperture with First Shot.
In this mode, the 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. See the ControlTL Center Point
section for more information.
To set the aperture and ISO values that will be aligned with the ControlTL center point:
1. Turn on your camera and transmitting MiniTT1 or FlexTT5, but wait to press your shutter button or take any pictures.
2. Set the aperture and ISO you wish to align with the center point. Set the shutter speed as desired, however changes
to shutter speed will not affect PowerTracking.
3. Press the shutter button to take a picture. The center point is now aligned with your aperture and ISO settings.
4. Use your camera’s FEC control to get the exposure the way you want it. If you are unable to achieve the exposure
you want using this control, try adjusting the Flash Exposure Compensation control in the PocketWizard Utility for
each PowerMC2, use a different aperture or ISO, or consider an AC3 ZoneController.
5. As you adjust your camera’s ISO and aperture, flash power output will automatically track to maintain the current
exposure level.
