10.4 Wireless lighting ratios made easy

When using multiple lights to light a subject it’s very easy to set up a light-

ing ratio between the Main and Fill lights. The ratio can be set from -3

stops to +3 stops.

Equipment needed:

• One Qflash 4d located at camera position

• One Qflash / 2/ 2d/ 4d located off to the side of the subject

• Two FREE

WIRE’s

• Two FW31 cables

• Two Quantum Turbo, 2x2, Z, or Compact Batteries

Set up:

Connect the equipment as shown.

Set the Main flash to TTL mode.

Set the Fill flash, located at the camera position to Auto mode. Select

an F number that is less

than the F number set on the camera. Typically

it is set to one stop under the camera’s aperture, but can be as low as

2 1/2 stops under.

Next use the options button on the Fill flash (see Section 5.9). Adjust

the Linked ratio for the difference between Fill flash and the cameras

aperture.

Example. If the camera is set for F8.0, and the Fill is set for F5.6,

the Linked ratio needs to be set to +1 ( the camera is one stop higher

than the Fill)
