Automatic switching to the flash sync speed fails to occur.
• The camera has a between-the-lens shutter (as do most compact cameras),
Switching to sync speed is therefore unnecessary.
• The camera is set to high-speed flash mode P-TTL-HSS.
In this case no switching to sync speed occurs.
• The camera operates with shutter speeds that are slower than the flash sync
speed. Depending on the camera mode, there is no switch to flash sync speed
(see the camera's operating instructions).
The shots have shadows in the bottom of the image.
• Because of parallax error between lens and flash unit, close-up shots may not,
depending on the focal length at the bottom of the image, be fully illuminated.
Tilt the main reflector downwards or turn the wide-angle diffuser in front of
the reflector.
The shots are too dark.
• The subject is beyond the range of the flash unit.
Note: Using bounce flash reduces the range of the flash unit.
• The subject contains very bright or highly reflective areas.
The metering system of the camera or flash unit is deceived as a result.
Set a positive manual flash exposure correction, e.g., +1 EV.
The shots are too bright.
• In close-up shots, overexposure (shots that are too bright) may result if the
shutter speed is faster than the flash sync speed. The minimum distance from
the subject should be at least 10% of the maximum flash range indicated on
the display.
The flash parameters for ISO film speed and the aperture (f-stop) cannot be
adjusted on the flash unit.
• There is an exchange of digital data between flash unit and camera through
which the ISO and aperture (f) values are automatically adjusted on the flash
unit. In this case the manual setting of ISO and aperture isn't possible!
