The H3D can be used together with most flash units in manual mode. However, to make use of a
TTL automatic function, you must ensure the flash 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 viewfinder houses an integral fill-flash with a guide number of 12 and features OTF/TTL flash
control. This unit is capable of providing enough illumination for many fill flash functions outdoors
as well as simple indoor shots at shorter distances.
Flash output can be adjusted separately from ambient exposure for optimum control.
Separate flash 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 an exposure).
Please see the relevant user manuals for information regarding separate flash units.
As with all strobe/studio flash use, very particular attention should be taken to ensure
correct connections and general handling practice. Potential dangers might increase
when cameras are also connected to electronic peripherals (digital backs, comput-
ers, lighting units, etc) and should diminish when IR and similar wireless flash 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.
Do not attempt to connect a flash unit dedicated for use with another camera brand
via the hot shoe. The flash unit and / or camera could be damaged.
General
When using the A or S setting together with flash, 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 flash close up or when using larger aperture settings, remember that the
flash unit’s output has a specific minimum duration which might still be too great for
correct exposure. Read the unit’s output specifications for further information regarding
any potential restrictions.
You can use the flash metering capability with external flash units of all kinds (TTL
flashes must be set to Manual mode).
Rear sync is a useful feature used either for effect or to produce a more ‘natural’ look
when combining long exposures involving light trails and flash.
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
flash unit is set to TTL or whether it is set to its own integral metering system (A).
Control of either the integral flash unit or separate SCA3002 compatible flash unit re-
garding the two functions, exposure compensation and shutter sync, is via the grip. The
flash measure function can be used for flash units that are not SCA 3002 compatible or
for SCA 3002 compatible units at manual setting.
Only flash units specially adapted for use with the H3D should be connected to the
hot shoe on the camera.
To change the balance between flash output and camera exposure requirements to
produce a variety of effects, use the exposure compensation function. For various long
exposure effects use the sync function. To make flash exposure tests use the flash meas-
ure function.
