Hasselblad CF DIGITAL CAMERA BACK RANGE User Manual page 59

Flash / Strobe
A CF digital back can be used together with
most studio or portable units.
The Hasselblad 503CW and 200 series cam-
eras also offer a TTL function if required.
Most flash/strobe units are suitable for use with the CF, with some combinations offering TTL. Check
the chart further on in this chapter to find the specific combination you intend to use.
Pay particular attention when using studio flash/strobe units and tethered to a stationary compu-
ter as this cable configuration guards against both personal injury and damage to equipment.
Portable units
All Hasselblad 500 series and SWC series cameras use the regular PC contact on the lens
for flash sync. 200 series models, FlexBody ArcBody and view cameras require other
configurations (see chart).
Studio flash/strobe units and tethered to a desktop computer
If the CF is tethered to a computer that is connected to a regular electricity supply system
as well as a studio flash/strobe unit that is also connected to a regular electricity supply
system/generator system, then make the following connections instead. For your own safety
and to protect the electronics in the digital back, please ensure you do this correctly.
a) Connect the flash input sync cable from the sync contact (PC connector) on the lens
to the flash sync IN terminal on the back.
b) Connect the flash output sync cable from the flash sync OUT terminal on the back
to a regular flash/strobe sync cable that is connected to the unit.
TTL function – (503CW only)
The reflective characteristics of the digital sensor are different to film surface charac-
teristics for which the TTL function was originally designed. However, by changing (in
effect, 'tricking') the setting, TTL exposures can be made. Proceed as follows:
Move the ISO selector on the 503CW so that is becomes approximately 1⅔ f/stop higher
than the ISO setting on the digital back. Therefore, for example, when the back is set at
50 ISO, the 'film speed setting' on the camera should read 160 ISO, and so on. Testing
for the most suitable compensation that suits you is recommended.
