5. Manual flash mode
Fig. 11: Shot with direct flashlight
In this mode, the flashgun will always emit its full power.
Adaptation to the actual picture shooting situation is by setting the
corresponding aperture on the lens.
A single value for the flash-to-subject distance appears on the LC display while in
manual mode.
If the displayed value does not coincide with the actual distance, then the aperture
and/or partial light output level have to be changed accordingly (see ch. 9, p. 32).
The decisive points for the partial light output level are:
• Distance to the subject
• Desired aperture
• ISO film speed
• Zoom position of the reflector
The sensitive selection of partial light output levels makes it possible
to adjust the distance to the subject in very small increments in the
manual flash mode.
