11. TTL and QTTL MODE OPERATION

TTL Mode

TTL mode may be used when the camera exposure is set to manual, aper- ture or shutter priority, or program mode, and Qflash is connected to the camera with a compatible QF series Adapter. The camera will determine flash exposure. The listing for compatible QF series TTL adapters is avail- able from your dealer, or at www.qtm.com. QF series TTL adapters are generally not compatible with digital cameras.

The exposure indications for TTL mode are similar to those of Auto mode with one exception. The amount of under or over exposure will not be shown in the display.

QTTL mode

When using a D, Dw, or Dw-R series QTTL adapter, “TTL” is replaced by ”QTTL” on the Qflash display. QTTL mode has all the features of the Auto Fill mode including adjustment of fill ratio. The difference is that QTTL mode lets the camera, not Qflash, control exposure.

Set your camera to manual, aperture or shutter priority, or program mode for QTTL dedication to Qflash 5d-R.

Some cameras allow compensation (+/-) for flash/fill ratio. Qflash 5d-R flash/fill can also be set on the QTTL adapter using the “Fill” dial. Choose any setting from –3 stops below to +2 stops above the camera’s aperture, in 1/3 stop increments. When desiring flash/fill ratio use either the camera setting or the QTTL adapter setting, but not both.
