color fi lm, and on instant recording fi lm. You can also record them on either 120 or 220 roll-
fi lm or on 70 mm long rolls (Figure 2-2). On all V system cameras, you can also produce the
images in the square or rectangular format.
Figure 2-2 Magazines for electronic imaging. A digital imaging back can be attached to most
Hasselblad cameras in the V system in place of a fi lm magazine. Some H cameras are, or can
be, equipped with various digital backs, an instant fi lm magazine HMi 100, or a fi lm magazine
HM 16-32 for 120/220 rollfi lm. H3DII cameras are supplied with a digital back and are for
digital imaging only.
The 2¼ 2¼ in. Square Format
Since 1947 many photographers selected Hasselblad V system cameras not only because of
the larger image format but because they liked recording images in the square format (Figure
2-3). The 2¼ 2¼ in. (6 6 cm) square format established the popularity of the medium-for-
mat cameras. The exact image size is 54 54 mm, with 12 images on one roll of 120 fi lm and
24 on the 220 type.
Many good points can be made about photographing in the square format. You do not
have to decide the fi nal image shape when you take the picture. A square can be changed
beautifully into a rectangular image without losing image sharpness if you leave the long
image side in its original length of 54 mm. You also do not have to decide which way to turn
the camera when you take the picture. The 12 square images from a 120 roll of fi lm make
beautiful proof sheets on a sheet of 8 10 in. paper, with all the images right side up, so you
never need to turn the proof sheet.
