Shutter
Shutter refers to the shutter of the camera the P+ back resides on.
Due to the sleeping architecture of the P 65+, where the CCD is put
to sleep to reduce power consumption, the P 65+ needs to wake up
before shooting. The timing of this wake up signal is referred to as the
latency.
In general, if the camera is used with 645 format cameras with digital
interface the recommended setting is “Normal latency”.
Zero latency has a shorter response time, but higher power consumption,
so when preserving battery life is a priority you should select “Normal
latency”.
If the P 65+ back is used in “two shoot mode” on a large format camera
with i.e. a copal shutter or other mechanical shutter where the shutter
is released one time for waking up the back, and another time for
making an exposure, then the shutter setting in the P 65+ must be set
to “Normal latency”.
Using “one-shot” cable and Zero latency P 65+ will respond immediately
triggering the camera.
Though Zero latency has a higher power consumption, the back will
still go to “power-down” mode when no media, cf-card, microdrice
®
or
computer, is available.
In general you should only use normal latency if you are using the
so-called two-shot release cable. If you are using Zero latency on
a two-shot release cable, you can very well end up having double-
exposures.
