the given camera).
The two established values for aperture and shutter speed can be set on the
camera because the camera’s shutter speed is slower than the camera’s flash
synch speed.
To maintain a balanced range of highlights, for instance in order to retain the
character of the shadows, it is advisable to select the automatic aperture on
the flashgun one setting lower than the aperture adjusted on the camera. In
the above example the camera was adjusted to f/8. Consequently, we advise
you to set an aperture of f/5.6 on the flashgun.
When shooting into the light, ensure that the backlight does not shine directly
onto the sensor as this will confuse the flashgun’s electronics!
8.2 Fill-in flash in manual mode
The partial light output levels can be used in manual flash mode to achieve
the required brightening effect of fill-in flash.
Complete illumination of shadow areas
Use the camera, or a hand-held exposure meter, to establish the required
aperture and set this value on the camera. The given range of the flashgun is
indicated on the calculator dial. If the distance to the subject is shorter than
the indicated flash range, then select a partial light output level to match the
distance.
Stepped brightening
Use the camera, or a hand-held exposure meter, to establish the required
aperture and adjust this value on the camera. To diminish the brightening
effect compared with full illumination of shadow areas, reduce the partial
light output level of the flashgun by one setting.
8.3 Fill-in flash in TTL mode
Some camera models automatically control fill-in flash when in program or
automatic modes. The manner of camera internal fill-in flash control varies
greatly between modern camera models, making it impossible to give a pre-
cise description of the individual adjusting procedures. These are normally
specified in the operating instructions for the given camera.
Shadows can also be brightened with a flashgun in TTL mode on cameras
that do not feature a special fill-in flash program or setting. In such cases the
effect of fill-in flash depends upon the characteristics of the camera’s TTL
metering system. Consequently, in many instances, it will be advisable to
adjust automatic mode for fill-in flash.
9. Auto-Check Display
The auto-check signal o.k. lights ቫ up only when the frame will be, or was,
correctly exposed in auto or TTL mode.
In this manner it is possible to manually fire a test flash while in auto mode so
that the correct aperture can be established beforehand. This is particularly
valuable with bounced (indirect) flash when reflection conditions are difficult
to judge.
A test flash cannot be fired in TTL flash mode. The test flash is triggered with
the manual firing button
ቨ.
If the auto-check display o.k. remains dark after a test flash, then adjust the
next wider aperture, or diminish the distance to the reflection surface of the
subject, and then repeat the test flash.
The f-stop established in this manner must also be set on the camera.
Hold the camera and the flashgun with photosensor in the same man-
ner as for the actual shot.
10. Illumination and Wide-Angle Diffuser
The wide-angle diffuser widens the horizontal lighting angle from 62° to 65°,
and the vertical lighting angle from 42° to 60°.
The wide-angle diffuser is intended for use with focal lengths of less than
35 mm (for 24 x 36 mm), and less than 75 mm (for 6 x 6 cm).
The wide-angle diffuser automatically diminishes the maximum flash ranges.
