User manual BOLEX H16 REFLEX

[. . . ] H 18 Reflex, . 1 We strongly recommend that a test roll of film is exposed in the camera when first purchased. This will help you to get to know it and will ensure that the instructions given in this manual have been carried out correctly. The camera is supplied with: 1 auxiliary multifocal viewfinder 1 filter holder on the camera 1 set of five filter holders 4 gelatine filters 1 rewind crank 1 folding rubber eyepiece 2 turret plugs 1 empty spool (100 ft. ) Throughout the world, Bolex cameras have acquired a reputation for unrivalled quality. The H 16 Reflex is the most advanced and comprehensive model in the Bolex range. It is appreciated not only by discerning amateurs and explorers but also by many professionals, scientists and those in the fields of industry and education. [. . . ] As a rule, very small diaphragm apertures should be avoided, as there is a risk of diffraction affecting picture quality. Moreover, with some film sensitivities and lighting conditions, even the smallest diaphragm opening cannot prevent over-exposure. As the variable shutter permits reduced exposure time without changing the filming speed, both these risks are greatly minimized and a neutral density filter is unnecessary. I ncreased picture definition. Closing the variable shutter reduces exposure time and thereby increases the sharpness of moving subjects. However, if the filming speed is not increased, this procedure can result in jerkiness on the screen. In special cases, where picture sharpness is more important than steadiness (such as frame-by-frame analysis of scientific phenomena, sports contests and motion studies), it is an advantage to be able to reduce exposure time, without changing filming speed, as this diminishes the blur caused by a moving subject, Increased picture sharpness is especially useful for projection on wide screens. To safeguard against the risk of jerkiness, due to the shutter being partially closed, the filming speed should be increased-for instance, to 24 f. p. s. or over when filming with the r half closed. 25 Loading the camera 2 Now that you are familiar with the various features of your camera and know how they are operated, you are ready to start loading. To avoid exposing the edges of the film to light, the camera should be loaded in a dimly lit place, well away from sunshine. Before loading the camera: 1. Move the selection knob (3) until the number corresponding to the desired filming speed faces the red dot. Wind the camera (page 16). 1 I nserting the film Lift the lid opening ring, turn It In the direction marked by the arrow 0, then lift off the lid. The inside of the camera is as shown in the illustration. Prepareto load the film as follows: 1. Check that the pressurepad pin (a) is locked and that the pressure pad cannot open. Remove the empty spool from its spindle by pressing ejector (b) and place the spool holding the film on the upper spool shaft (film should run in the direction indicated by the engraved arrow). shiny side of the film (the backlnq) should face towards the back of the camera and the light matt side (sensitized) towards the lens. Using the film knife, cut off the end of the film diagonally between two perforations, as shown in the illustration. Close the loop formers by moving the control lever parallel to the pressure pad. · __ . _ ··· ~N~ ~ ~. -< ". , , I~ 27 5. Press the release while simultaneously pushing the end of the film against the sprocket (illustration opposite). Continue to depress the release until 10 to 12" of film have passed through the drive mechanism. (If you accidentally leave them closed, they will automatically open when the camera lid is replaced. ) 8. Insert the end of the film into the slot in the core of the take-up spool. Rotate until about three turns of film have been taken up and place the spool on the lower spool shaft. [. . . ] The Bolex lightmeter is designed for motion filming and especially calibrated for use with the H 16 Reflex camera. I L 45 Bolex matte box. Acts as a highly efficient lens hood and can also be used as a portable accessory for titling and trick effects, such as entering a room through the keyhole, making the same character appear several times on the same picture, framing a landscape in binoculars, etc. For filming at very close range, focusing is simplified by the geared guide plate which allows for continuous increase in the lens focal length. Gives a good firm grip on the camera, thereby increasing camera stability. [. . . ]
