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.
