Fill/flash — QTTL D series adapters provide for fixing fill/flash ratios

between the camera’s exposure and the flash’s exposure.

Both fill/flash and Linked ratios can be set independently. Here’s an exam-

ple of using both ratios:

A QTTL adapter is connected to a camera set to f/8. A Control Qflash in

Auto Fill mode is connected to the QTTL adapter. The R Fill dial is set to

-2 stops. The light produced by the Control Qflash will be F/4, 2 stops less

than the camera.

A Remote Qflash off to one side is Linked to the Control Qflash at +2

stops. The light produced by this flash will be f/8, 2 stops above the

Control Qflash. In this example the Control Qflash located at the camera

position provides the “fill” light while the Remote Qflash provides the

“main” light.

7.1 Wired Control Mode using only Qflash 4d’s

Qflashes are connected with cables such as QF50 for the Wired Control

mode.

Linked mode is available when the Control Qflash is set to Auto mode.

Even more lighting versatility becomes available when a D series QTTL

adapter is connected to a camera. Then Auto mode is replaced by “A

FIL

”

(Auto Fill) mode, and in addition to a Linked ratio between Control and

Remote Qflashes, a flash/fill ratio can be set between the camera and the

Control Qflash.

When desiring camera control of exposure using a D series adapter, QTTL

mode replaces TTL mode. The QTTL mode does not provide the Linked

ratio of Auto or Auto Fill modes, however it lets the camera control flash

exposure. The sections that follow explain in detail how to use multiple

Qflashes in Wired Mode.

7.1.1 Setting the Wired mode and the Control flash

The diagram shows a set up for Wired Control. The number of Qflashes

can be 2 or 3. Turn on all Qflashes. The Qflash displays will prompt you to

select the Control flash.
