H4D
The H4D can be used together with most ash units in manual mode. However, to make
use of a TTL automatic function, you must ensure the ash unit is compatible with the
SCA 3002 system. Connection is either by the PC socket or by the hot shoe (see warning
note below).
The viewnder houses an integral ll-ash with a guide number of 12 and features OTF/
TTL ash control. This unit is capable of providing enough illumination for many ll ash
functions outdoors as well as simple indoor shots at shorter distances.
Flash output can be adjusted separately from ambient exposure for optimum control.
Separate ash units can be used in dedicated mode when connected to the hot shoe
if the unit is compatible with the SCA3002 (Metz) system using a Hasselblad SCA3902
adapter. This provides a cable free link up for information transfer.
Flash synchronisation can be set to normal or rear (the beginning or end of a capture).
Please see the relevant user manuals for information regarding separate ash units.
General
When using the A or S setting together with ash, the exposure requirements of the
camera will dominate which might produce slow shutter speeds indoors, for example,
requiring the use of a tripod. If, on the other hand, you select P or Pv instead, then a
shutter speed of 1/60 or faster is automatically chosen by the camera enabling you to
hand hold.
When using ash close up or when using larger aperture settings, remember that the
ash unit’s output has a specic minimum duration which might still be too great for
correct exposure. Read the unit’s output specications for further information regarding
any potential restrictions.
You can use the ash metering capability with external ash units of all kinds (TTL ashes
must be set to Manual mode).
Rear sync is a useful feature used either for eect or to produce a more ‘natural’ look
when combining long exposures involving light trails and ash.
When using suitable dedicated units (compatible with SCA3002), adjustments are made
automatically and governed by the settings on the camera. This applies to whether the
ash unit is set to TTL or whether it is set to its own integral metering system (A).
Control of either the integral ash unit or separate SCA3002 compatible ash unit
regarding the two functions, exposure compensation and shutter sync, is via the grip.
The ash measure function can be used for ash units that are not SCA 3002 compatible
or for SCA 3002 compatible units at manual setting.
To change the balance between ash output and camera exposure requirements
to produce a variety of eects, use the exposure compensation function. For various
long exposure eects use the sync function. To make ash exposure tests use the ash
measure function.
Note
As with all strobe/studio ash use,
very particular attention should
be taken to ensure correct connec-
tions and general handling practice.
Potential dangers might increase
when cameras are also connected
to electronic peripherals (comput-
ers, lighting units, etc) and should
diminish when IR and similar wire-
less ash release devices are used.
Victor Hasselblad AB and Hasselblad
A/S can accept no responsibility
whatsoever for accidents that might
occur or damage caused when
Hasselblad equipment is used in
combination with third-party units
of any description.
Note
Do not attempt to connect a ash unit
dedicated for use with another camera
brand via the hot shoe. The ash unit
and / or camera could be damaged.
Note
Only ash units specially adapted
for use with the H4D should be
connected to the hot shoe on the
camera.
Note
If using ash/strobe as the main light
source and 1/800s shutter speed,
remember to turn o the True Exposure
facility (Custom Option #13).
