THE HASSELBLAD MANUAL
IMAGE FORMAT
The Hasselblad XPan is made for 35 mm fi lm in the standard cassettes but the images can be
produced either in the standard 24
36 mm format or in a panoramic format of 24 65 mm
and you can mix the two in any desired fashion on a roll of fi lm. The format change is made
by moving a single control, which also adjusts the viewfi nder and the frame counter so that
all images are always properly spaced on the fi lm (Figure 20-6).
Film Processing
If all images on a roll of fi lm are in the standard 35 mm format, the fi lm can be processed and
printed anywhere. If all or some of the images are in the panoramic format, you need a lab
that can return the fi lm to you without cutting it. Request that the fi lm be returned in a strip
so you can cut it yourself. Prints from panoramic images must be made in a custom laboratory
unless you make them yourself with a 6
7 negative carrier. Panoramic transparencies need
a 6 7 slide projector which is diffi cult to fi nd.
LENSES FOR XPan CAMERAS
Three lenses are available: a 45 mm f /4 standard and a 30 mm f /5.6 wide angle both focus-
ing down to 27 in. and a 90 mm
f
/4 telephoto that focuses as close as 39 in. The three lenses
perform as 30, 45, and 90 mm lenses in the 35 mm format. In the panoramic format the 45 mm
lens covers an area along the long panoramic side equal to a 25 mm focal length on the
35 mm format, the 90 mm is equal to a standard 50 mm, and the 30 mm covers a panoramic
area equal to a 17 mm lens on the 35 mm format.
Attach the lens to the camera by aligning the index on the camera and lens and then
turning the lens clockwise until you hear a click. The viewfi nder automatically adjusts to
the focal length of the lens on the camera, except with the 30 mm wide angle lens, which
is supplied with a special viewfi nder that is attached to the fl ash shoe on the camera. The
30 mm lens, similar to the other two lenses, is focused with the split-image rangefi nder in the
camera viewfi nder. Remove the lens by pressing the lens release button and turning the lens
counterclockwise.
Image Illumination
All XPan lenses are optically designed to cover the wide panoramic format but as some
light rays enter at a steep angle, a slight darkening at the edges and corners of the image
may become noticeable on transparencies taken with the 30 mm lens at any aperture and
with the 45 mm lens at apertures
f /8 or larger. You can eliminate the darkening by attaching a
center gray fi lter (supplied with the 30 mm lens). This fi lter should be on the 30 mm lens for
all panoramic images. You may want to use such a fi lter on the 45 mm lens when photograph-
ing at apertures of
f /8 or larger. Avoid apertures of f /16 and f /22 if possible for panoramic
pictures.
