16.2 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 5d-R
• One Qflash
(any version)
located to the right
of the subject
•Two FreeXWires
•Two QF30 cables
•Two Quantum
Turbo 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 Adjust the Linked ratio for the difference between Fill flash and the
camera’s 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)
