Proceed as following: Set the zoom knob to the longest focal length (56 mm). [. . . ] This combination provides a sharp image from about 6';' feet to infinity, even in relatively poor light. 10 Depth of field The depth of field is the zone of sharp focus and depends on the focal length, the lens aperture and the focusing distance. By pressing the red locking button, the switch' can be moved to "+ 1" or "-1 ", or to intermediate positions corresponding to "+ '12" or "- '12". At the + 1 setting the diaphragm is opened by one stop which is useful for backlighted shots, portraits against large bright areas. At the - 1 setting the diaphragm is Closed down by one stop to reduce exposure (for shots from a dark doorway, for instance). 12 The diaphragm locking system The diaphragm locking system permits setting the aperture to provide correct exposure for a certain subject area within a scene. This is helpful in scenes with great contrast - a person in front of a bright background, a spotlighted performer on a dark stage, for instance. button If the meter is used normally and automatically in such cases, the dark or bright background area influences the diaphragm setting, thereby underor overexposing the main subject. The diaphragm locking system can be used to overcome exposure problems in such cases. Using the diaphragm locking system, perfect exposure can be obtained as follows: a) Screw the cable release in the socket for diaphragm lock. b) Zoom in so that the view through the finder shows the main subject only (no background area). c) After having turned the little crown anti-clockwise, lock the diaphragm in set position with the cable release lock. d) With the diaphragm locked, zoom back to cover the desired area and film. e) At the end of the exposure, unscrew the . . The actual setting is done by means of the zoom knob, and must be done accurately because of the shallow depth of field (see last-but-one page of the Instructions). Chart above shows area coverage at diferent distances with the focus setting at infinity and zoom knob in macro range. When turning the zoom knob out of the macro range, the macro button jumps out and prevents accidental turning of the knob back into the macro range. 6" 4" 4" 2'/, " 2-'/'" 1-'/'" 1-'/'" 6'/'" Special effects and transitions The Bolex Macrozoom® lens allows you to make special effects, heightening the interest of you r film: you will be able, for example, to film slides or titles that you wish to include in your film (see "Bolex Macro Set" under "Accessories available separately", page 18); you will also be able to create smooth and pleasing transitions from one scene to the next. By zooming from a long shot into the macro range, a pleasinq and effective focus transition from a distant to a close subject is obtained. Vice versa, a continuous focus transition from a close to a distant subject is obtained by turning the zoom knob out of the macro range. A scene can be ended by turning the zoom knob into the macro position (after pressing the macro button), thereby throwing the subject completely out of focus. The next scene can be "focused in" by turning the zoom knob out of the macro position until the subject is in sharp focus. When the camera is not used over extended periods, remove the batteries from the battery container and store them in a cool place. Damage to the camera through leaking batteries is not covered by the guarantee. (Do not rub hard - this may damage the lens coating. ) Open the lid and clean the cartridge compartment with a brush. (Do not keep the camera in glove compartment or on the window shelf of your car. ) 17 Accessories available separately ~ l>~!_;:;:: ~'" ;::'s"· . ::, of $ , Bolex accumulator chargers For description and use of these Bolex chargers, see page 4. [. . . ] Film the visitors to an exhibition from above, taking one frame every second: on the screen, you will see them move jerkily, frantically and funnily. Take a shot every ten seconds after framing a portion of sky with moving cloud formations: on projection, you will see a wild turmoil of clouds, breaking up, turning and twisting in torment. From very close to, take a shot about every two minutes of a tulip opening (the steadiness of the subject is then as important as that of the camera): on your screen, you will see it open its corolla in a few seconds. By giving free rein to your imagination, you will find a thousand aod one subjects similar to the three suggested above, lending themselves to single-frame filming and successful enough to be included in your film.
