Wireless Ratios with Remote Flash
Controlling E-TTL Ratio Flash with PocketWizard’s MiniTT1 and FlexTT5 and the Canon flash system is easy. The ControlTL system seemlessly transmits the ratio commands from your on-camera flash to your remote flashes. Simply leave your remote flash in basic E-TTL, place in the remote FlexTT5's hot shoe, and set the A-B-C Zone selector on the FlexTT5 to put your remote flash in the right zone or slave group. Control the balance of light between your on-camera and remote flashes using the familiar Canon flash controls.
NOTE: The Wireless Ratios with on-camera Flash video explains ratios when using an on-camera flash. This video, Wireless Ratios with Remote Flash, explains how to manage ratios with your on-camera flash not contributing light to the scene and acting just as a ratio controller.
Here's how to get started,
With camera-mounted MiniTT1 or FlexTT5 turned OFF, slide a 580EX II into the PocketWizard’s dedicated hot shoe and lock it in place.
Enable MASTER mode for the on-camera flash: press and hold the ZOOM button on the 580EX II until the flash icon and “OFF” appear. If you are using the original 580EX, just set the OFF/MASTER/SLAVE switch to MASTER and skip to Step 4.
Turn SELECT dial to see blinking “MASTER + ON”
Press the SELECT button in the center of SELECT DIAL.
MASTER mode is now set.
Now enable Ratio mode for the on-camera flash: Press the ZOOM button TWICE to see RATIO + OFF blink.
Turn the SELECT dial to see ON + RATIO + A B
Press the SELECT button. MASTER Ratio mode is now set.
Now set the on-camera flash to not contribute light to the scene: Press the ZOOM button THREE TIMES to see the flash icon + ON.
Turn the SELECT dial on the flash until you see OFF.
Press the SELECT button. The on-camera flash is now set to not contribute light to the scene. Set the on-camera PocketWizard to C.1 or C.2.
Slide a compatible Canon Speedlite into the dedicated shoe of a receiving FlexTT5, lock it onto the shoe. Set it to C.1 or C.2 and switch the flash unit ON.
Set one of the FlexTT5 Zone Selector switches to “A” and the other to “B.”
Do not set the remote flash to SLAVE mode or worry about matching the Canon Channel. The FlexTT5 handles all of that for you. Just leave the remote flash in basic E-TTL mode.
Now simply turn the SELECTOR dial on the camera-mounted 580EX /EX II controller to change the flash ratio to make remote flash “A" brighter or make remote flash “B” brighter.
Ratio with ST-E2
You can also use the compact Canon ST-E2 Speedlight Transmitter with the PocketWizard MiniTT1 or FlexTT5 for ratio control.
Slide the ST-E2 on the hot shoe of the MiniTT1 or FlexTT5 mounted on your camera.
Slide a compatible Canon Speedlite into the dedicated shoe of two receiving FlexTT5 units, lock them onto the shoes and switch both units ON.
Set one of the FlexTT5 Zone Selector switch to “A” and the other to “B.”
Do not set the remote flash to SLAVE mode or worry about matching the Canon channel. The FlexTT5 handles all of that for you. Just leave the remote flash in basic E-TTL mode.
Press the “Ratio On” button on the ST-E2 to enable ratio control.
Now simply press the “left” button to make flash “A” brighter or the “right” button to make flash “B” brighter.
