Figure 2-18. Recock Link Drives Taking Mirror Carrier into Position for Exposure
As described in the Exposure section of the Sequence of Operations, ambient and wink measurements are
now made, strobe fire aperture selected from the lookup table, Solenoid 1 released, blade position carefully
monitored and the strobe is fired — all under microprocessor control.
To end the exposure, Solenoid 1 is again energized to close the shutter blades. If the Far Lens was used for
the exposure, it is now unlatched and spring-returned to its normal position, out of the optical path. The
exposed frame is now ready for processing.
