Error messages will appear if you choose a fill ratio which is out of range of the flash. The error indications are:

“OUT OF RANGE - DECREASE FILL OR F#”

For example, the camera is set to F16 and QTTL fill flash is set to +2 stops. Either decrease the f/# on the camera or decrease the fill flash ratio on the QTTL adapter.

“OUT OF RANGE - INCREASE FILL OR F#”

For example, the camera is set to F2.8 and QTTL fill flash is set to –3 stops. Increase the f/# on the camera or increase the fill flash ratio on the QTTL adapter.

Once the adjustment is made and Qflash returns to an acceptable range, the display will revert to the usual Auto Fill information.

10.4 Auto Sensor Limit

Setting Qflash to Auto exposure makes picture taking fast and easy. However, an automatic flash has a flaw: the sensor on the flash expects the subject to be wide, flat, and fill the view of the sensor. A person standing against a wall fits this description; people in a catering hall or in a park at night do not. When the background is located far behind the subject, the automatic flash struggles to produce even lighting. The result is often an over exposed subject, sometimes by as much as two stops. When a photo lab develops film with a greatly over exposed sub- ject, it will ‘print down’ to bring the flesh tones back into range. Or, time will be spent adjusting a digital image, with the resultant loss of detail and image quality.

To solve this problem use the Flash sensor limit.
