The shutter-release button of the Nikon F2SB Photomic camera is fitted with a fingerguard that also doubles as the shutter operation mode selector. Set to the middle position, the fingerguard provides for normal shu tter release via the shutter button. To lock the shutter to pre- vent accidental release, lift up and turn the fingerguard until the index dot aligns with the "L" (lock) marking. For time exposures preset via the camera's built-in self- timer, lift up and turn the fingerguard until the index dot aligns with the "T" (time) marking. (See "Time Ex- posures" on page 25 for details.)
The built-in self-timer can be used to trip the shutter after a delay of from 2 to 10 seconds. The numbers marked on the timer scale indicate the delay in seconds. To take a picture using the self-timer to fire the camera, first set the aperture and shutter-speed controls, advance the film, and cock the self-timer by turning its lever downward until the index line (on the lever) aligns with the figure (on the scale) corresponding to the desired number of seconds delay; then, simply press the small button just above the timer to start the countdown, with shutter release occurring at the completion of the cycle. Note that the self-timer can be set either before or after advancing film; also, if you decide not to use the self-timer after setting it, simply use the shutter button in the normal way to make the next exposure and to release the self-timer for resetting to the off position. The self-timer may not be used at the "B" shu tter-speed dial setting.
