EXPOSURE OPERATION
To obtain accurate exposure: first align the film-speed setting line (engraved on the Inner Dial) to
coincide with the small black dot engraved beneath the selected film speed rating (ASA or DIN). Next,
point the camera lens to the subject and ensure that fingers do not obscure the photo-electric window
(mounted above the lens). Note the position at which the needle comes to rest. Now, rotate the knurled
Outer (shutter speed) Dial until the small 'zero' index is bisected by the stationary meter-needle (located
in the curved window). The meter is now primed for any selection of coincident reading of aperture and
shutter speed. Finally, align the red dot on the Hellos lens with the selected aperture: point the camera at
subject, rotate the focusing ring until sharp image-resolution is obtained, turn the pre-set diaphragm ring
clockwise to its fullest extent--depress the release button to obtain perfect exposure.
