7.2.4 One Qflash in

Auto mode, one in

Linked mode

With the Qflash Model

T/T2/T2d in Auto mode, the

TTL mode of the Qflash 4d

is replaced by Linked

mode. The ‘Linked’ unit’s

light output will be con-

trolled by the sensor of the

unit in Auto mode. Use this

set up when you want more

light than that available

from one Qflash, or when

you want light from two

directions, controlled by the

Qflash near the camera, for

example.

7.2.5 Using Qflash 4d to set up lighting ratios

This set-up lets a Qflash 4d ratio the light from any number of Qflash or

Qflash 2’s.

With the Qflash T4d in Auto mode, the TTL mode of the Qflash Model T/T2

is replaced by Slave mode. The ‘Slave’ unit’s light output will be con-

trolled by the sensor of the T4d.

The output of the ‘Slave’ unit can be set up as a ratio of the T4d, using the

Linked Ratio in Option menu #1. The Linked Ratio is shown on the Option

menu #1 only.

By setting the linked ratio to +1, for example, you can achieve a true 3:1

ratio at the camera position. In this example, the output of the ‘Main’ will

be one stop higher than the output of the ‘Fill’ at the camera position.

Qflash 4d will prevent setting a linked ratio outside the possible f#/ISO

combinations. For example, if Qflash 4d is set to f 2.0, ISO 200, you can

set a ratio only between 0 to +3 stops.

Linked Ratio can be set on Option menu #1, as described in Section 5.9.
