Selecting The Shutter Type And Camera Operation - Hasselblad Digital Camera Manual

The XPan is shaped like a 35 mm camera, and the pictures are made on 35 mm fi lm in
standard cassettes with 36, 24, or 12 exposures. The images on the 35 mm fi lm can be made in
the standard 24 36 mm size or in a 24
with a simple turn of a knob, which automatically adjusts the viewfi nder image and the frame
counter in the camera. You can produce images of both formats on the same roll of fi lm.

SELECTING THE SHUTTER TYPE AND CAMERA OPERATION

During the Hasselblad history, cameras have been produced where the fi lm needs to be
advanced manually and models with a motorized fi lm transport. There also have been camera
models with focal plane shutters in the camera and others with shutters in the lenses.
Focal Plane Shutters
All Hasselblad cameras in the 200, 2000, and 2003 series, and XPan models have focal plane
shutters that provide short shutter speeds up to
second on the medium-format models.
A focal plane shutter scans the image area from side to side or top to bottom. As a result,
different image areas are exposed to light at different times. The fl ash must fi re when the
shutter is open over the entire image area; otherwise, only part of the area is exposed. Flash
pictures must be made at slower speeds. The top shutter speed for fl ash is
1
the XPan and / second on the other V system Hasselblad focal plane shutter models (see
90
Figures 1-1 and 1-2).
Figure 1-1
With a focal plane shutter, the image is exposed progressively by a slit that moves
across the image area. (1) The shutter curtain is closed. (2) The fi rst shutter curtain moves,
creating a slit that begins the exposure. (3) The second shutter curtain follows the fi rst.
(4)The shutter is closed.

At longer shutter speeds, the second shutter curtain begins to move only after the
fi rst has reached the other side. Flash synchronization is possible at the moment when the
entire image area is uncovered (3).
