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

priority, however, Qflash will emit the fixed amount of light shown on

its display. Note that only the camera controls the F# and ISO shown on

the display- you cannot change it on Qflash. The distance shown on the

Qflash display will correspond to the correct distance for good exposure

for the F# selected. The camera also selects its shutter speed consistent

with flash exposure.

6.3 Auto Fill mode

The camera exposure may be set to shutter or aperture priority, or

manual when Qflash is set to Auto Fill mode. Light output is con-

trolled by Qflash.

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

replaced by the Auto Fill mode. The F# setting on Qflash tracks the F#

setting on the camera, and the ISO tracks as well.

Auto Fill mode provides fill/flash ratio control even for cameras that do not

support their own TTL fill/flash. Auto Fill is also useful when you prefer

Qflash to control exposure, instead of a camera’s own TTL or pre-flash

metering. Many photographers find that Auto Fill mode provides more

consistent exposures for digital cameras exposures.

In Auto Fill mode aperture and film speed information come from the cam-

era and cannot be changed on Qflash Fill flash ratio may be set using the

“R Fill” dial on the QTTL adapter. Choose any setting from -3 stops below

to +2 stops above the camera’s aperture, in 1/3 stop increments. As the

aperture of the camera changes Qflash will adjust it’s output to keep the

ratio that has been selected.
