The best way to arrive at critical definition is to turn the focusing mount of the lens slowly to and fro while observing the subject to be
focused on the ground glass. As you turn the mount, the image becomes more and more sharp up to a certain point, beyond which it
will again lose definition. At this "beyond" stage, turn the mount back again, narrowing down the degree of movement until you arrive
at the point of best definition.
The Hasselblad has a magnifier built into the focusing hood to determine the point of best definition. To bring it into action push the
hood opening cath fully to the right. When closing the hood, fold the magnifier back first.
The orthodox way of focusing with the ground glass screen may be adopted for taking photographs of subjects that are fairly
stationary. A different method of focusing is required when taking subjects in motion. Set the lens to a distance at which the subject
will be in a given moment, or focus at some spot which it actually has to pass and press the release button when the subject is
reaching the prefocused point.
With subjects liable to react self-consciously (e.g. children) set the lens to a suitable distance, and then approach the subject, exposing
as soon as the screen image appears sharp.
Alternatively, focus at some object which is at the same distance from the camera as the subject, but in a different direction. When
you have found the range swing round to press the release button as soon as the subject slip, into the field of view of the finder.
Shooting
Practise the following operations first with the empty camera with its film magazine in position until you can do them practically
automatically.
1. Wind the film transport. This advances the film and film counter, tensions the shutter, opens the aperture (in C models) and
brings down the mirror ready for the next exposure.
2. Open reflex hood to focus for a preview of the picture you want to take.
3. Set the exposure. Adjust the shutter for the right amount of light for the subject conditions (see page 32).
4. Select the aperture-speed combination you want to use; smaller apertures for greater depth of field (page 48) or faster speed to
arrest movement (page 47).
5. Determine the exact picture area and focus.
6. Release the shutter gently.
HOLDING AND CARRYING
For eye-level shooting, the pentaprism (above left) fits on top of the camera in place of the waist-level hood. Hold the camera up
to the eye, looking directly through the eyepiece at the back. With the sports finder (above right) turn the camera sideways so that
the sports finder is on top in its shoe on the side of the camera (above right).
The normal hold consists in supporting the camera round the neck with the carrying strap, and steadying it with the left hand. The
left index finger is on the release button, while the right hand focusses the lens. The right hand also operates the winding knob
after every exposure.
Two special holds for unusual occasions. To shoot over the heads of a crowd, hold the camera upside down above your head and
look up into the finder hood (above left). To get unobserved shots of people turn the camera round sideways (above right) so that
the lens points past your left arm. You see what is going on by looking down into the finder, although you are facing at right angles
to the shooting direction of the camera.
