9.2 Manual mode with QTTL adapter connection
With a QTTL adapter the camera controls the f/# and ISO shown on the
display - you cannot change it on Qflash. The camera also selects its shut-
ter speed consistent with flash exposure. The camera exposure may be
set to manual, aperture or shutter priority.
The power level is set on the Qflash. Qflash will emit the fixed amount of
light shown on its display, and the distance shown corresponds to the sub-
ject distance for good exposure for the f/# set on the camera.
The following QTTL features are available: Front or Rear curtain sync,
Auto focus assist, and Ready light.
9.3 Manual shooting made easy
Nothing can beat the combination of a flash meter and a flash set manu-
ally. Automatic and TTL are a compromise based on the need for speed.
Setting the flash for a manual power setting and taking an incident meter
reading takes time and resources the average photographer may not
have. So we use automatic flash exposure and know that in some situa-
tions the sensor may be fooled.
The Qflash 5d-R allows for easy manual shooting without metering. Below
is an example of how this is accomplished.
In this example Qflash will produce an F8.0
at the subject (8 ft), and it will be quickly
accomplished without metering.
Start by selecting the F number and Film
speed you are using on your camera. If you
have connected a QTTL adapter these are
already chosen for you. Now adjust the
power setting until the Qflash distance
shown matches the subject distance as
closely as possible.
