Hasselblad H3DII - Tethered Operation with Computer

40
Tethered to a computer
When tethered to a computer, you can control many camera functions using Phocus so-
ware. Even if you never shoot while connected, you will probably connect the camera to
your computer each time you want to download your images, though you might instead
use a compact-ash card reader and/or connect your ImageBank-II directly.
Connecting to a computer
To connect to a computer, simply attach a FireWire cable from the FireWire port on
your computer to the port on the side of the digital capture unit. e port is protected
behind a hinged cover.
Shooting with Phocus running

(not all computers supply power here, notably laptops). This will help conserve
the battery power of the H3D II. However, you must still have a charged battery

When initiating a shot from Phocus, the computer sends a signal to the digital capture
unit, which triggers the shutter and strobe/ash (if any). e digital capture unit then
sends the image back over the FireWire connection to the computer, where it is displayed
on the computer screen and saved as a 16-bit 3F le in the currently selected folder of
the computer hard disk.
3FR is a proprietary Hasselblad format for storing raw captures. It contains the complete raw
image exactly as it was captured by the camera, plus technical details that enable Phocus
to process and display the image correctly, amongst other things. is 3FR le is converted
into a 3F le (denoted by each le now bearing the sux “.f”) that furthermore stores
a complete history of the Phocus settings that you have applied to each image and stores
meta-data such as camera settings, image name, photographer, copyright, etc.
If you prefer not to correct and adjust your captures in Phocus, then you can export con-
verted 3F les from Phocus (and Aperture/Mac OS 10.5.2) directly to DNG, TIFF or PSD
and use Adobe Photoshop, for example. (Please note that a direct export will not enable
DAC and those benets will therefore be lost).
Please refer to the Phocus Soware Reference manual for further instructions about using
Phocus.
