14.1 QTTLw - Wireless TTL mode

QTTLw mode gives exposure control of all Qflashes to your camera’s pre- flash evaluative TTL metering system. Both Local (on-camera) and Remote Qflashes will produce the same exposure. The Fill ratio can be adjusted on the QTTL adapter (or on the camera, if available). However, use only one Fill compensation at a time.

Set the camera modes: Choose manual, aperture priority, or shutter priority on your camera. Program mode may be selected, although the camera will make decisions that reduce your control of lighting.

14.1.1A Local Qflash is optional.

If a local Qflash is attached to the camera, Press Mode I, the Up J/Down L until “QTTL” or “QTTLw” appears on the display.

Note: “QTTLw” will appear after the QTTL adapter has established com-

munication with the camera. This occurs when the camera shutter is pressed 1/2 way.

14.1.2 Set up the Remote Qflash(s)

Connect a FreeXWire receiver to the remote Qflash(s). FreeXWire model FW7Q connects directly to Qflash; models FW8R or FW10w require an FW31 cable for connection.

Press Mode I on the Remote Qflash, then press the Up J/Down L but- tons until the display shows “Linked to Local”.

14.2 QTTLwR - Wireless Multiple Flash Ratio TTL mode

QTTLwR mode provides the photographer with the ability to set three zones of flash exposure, each with different amounts of exposure offset from the camera’s TTL system. The three available flash zones are : Local, Group R1, Group R2. Any number of Qflashes can be employed in each of the 3 groups. For example, an on-camera flash could be set 1.3 stops down (Local), two main flashes on the left to +1 stop (Group R1), and a hairlight to –2 stops from the camera TTL exposure (Group R2). The actu- al settings could be whatever you wish within +/- 3 stops.
