range of the flash. The error indications are:

“OUT OF RANGE - DECREASE FILL OR F#”

Either decrease 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 adjustments return Qflash within its range, the display will revert

to the usual Auto Fill information.

6.4 QTTL mode

The camera exposure may be set to manual, aperture or shutter pri-

ority, or program, when Qflash is set to QTTL mode.The camera con-

trols the flash exposure.

When using a D series QTTL adapter the usual Qflash TTL mode is

replaced by QTTL mode. QTTL mode has all the features of the Auto Fill

mode described above. The difference is that the camera, not Qflash, con-

trols exposure. All features including adjustment of fill ratio are active. In

addition, the Qflash display shows the type of QTTL adapter in use.

Set your camera to shutter or aperture priority auto exposure, manual or

program mode for QTTL dedication to Qflash 4d.

Some cameras allow compensation ( +/-) for flash/fill ratio. Qflash 4d

flash/fill can also be set on the QTTL adapter using the R Fill dial. When

desiring flash/fill ratio use either the camera setting or the QTTL adapter

setting, but not both.
