Advanced Wireless TTL
Next recommended reading: Manual Flash
This section talks about Advanced Wireless TTL where you can use groups or zones of Speedlights and adjust the
light levels among them while still letting the camera make the exposure decisions. You may also want to read about
Manual Flash.
Make sure you read the Getting Started section first!
All references to TTL on this page refer exclusively to Canon's E-TTL II system, or Nikon's i-TTL/CLS.
Film TTL or earlier digital TTL systems are not supported.
"Speedlite" and "Speedlight" are used interchangeably. Either may be used to refer to Nikon or Canon's hot shoe flashes. Nikon or Canon specific
information will be noted as needed.
REMINDER: Speedlights mounted on a remote FlexTT5 should be set to their standard i-TTL/E-TTL mode. Do not use <MASTER>, <REMOTE>
or <SLAVE> modes on a remote flash.
Canon E-TTL II
Here are some tutorials discussing Canon Wireless Ratios or Manual operation:
• Wireless Ratios with on camera Flash
[1]
This tutorial talks specifically about ratios with a MASTER flash on
camera contributing light to the exposure in Zone A, and adjusting ratios with a remote flash in Zone B.
• Wireless Ratios with Remote Flash
[2]
This tutorial talks specifically about ratios with a flash on camera which is
NOT contributing light to the exposure, and is only used for AF-Assist and as a ratio controller for adjusting
remote flashes in Zones A and B. It also talks about using an ST-E2 as a ratio controller.
• Remote Manual Flash Control with a 580EX II
[3]
This tutorial talks about controlling the manual level of a
remote Speedlite from a 580EX II in Manual Master Mode.
Nikon Advanced Wireless CLS / i-TTL
Here is a video specifically discussing Nikon MASTER flash operation
[4]
.
1. Slide the MiniTT1 Transmitter onto the camera and tighten the locking ring.
2. Slide a Nikon SB-900 or SB-800 Speedlight onto the MiniTT1 radio.
• Set your Speedlight for MASTER = ON and enable remote groups/zones per Nikon instructions. The Nikon
SU-800 Wireless Speedlight Commander may also be used.
3. Set remote FlexTT5 radio to desired remote group/zone (A, B, C) using FlexTT5 zone switch.
4. Slide Speedlight onto remote FlexTT5 Transceiver. Set Speedlight for standard i-TTL mode (not REMOTE or
MASTER). Repeat for each remote Speedlight. All remote i-TTL Speedlights on the same group/zone will be
treated as one zone of light.
5. Adjust flash output level compensation using MASTER Speedlight flash controls.
6. Make sure all your PocketWizard radios are on the same channel and take pictures normally.
IMPORTANT: Nikon Speedlights set to REMOTE = ON and connected to remote FlexTT5 radios will not function
properly as remotes. You must be in normal i-TTL mode for remotes to operate properly. Turn off REMOTE or
MASTER for your remote Speedlights. Set desired Nikon remote group/zone via remote FlexTT5 zone switch.
PocketWizard channel is used instead of Nikon channel. ISO, aperture,aperture, flash exposure compensation (FEC),
and other settings will work with exposure normally via the PocketWizard ControlTL system.
