Power management and shutter latency
The CCD on the P back constantly needs to be
cleared from previous data before an exposure. This
requires some power consumption. On electronically
controlled camera bodies the power consumption
can be drastically reduced by setting the shutter
latency to long latency in the P back or inside the
Capture One Application (Please see the section
specific for your camera body for more information
on what latency setting to select).
Double exposure protection
It is not possible to accidentally double expose the
image by capturing one image quickly after another
when the P back is used on i.e. Mamiya 645 AFD or
Hasselblad 555 ELD. The electronic communication
with the body ensures that the P back is ready before
allowing release of the next shot. On other camera
bodies not using the electronically interface from the
P back, the user has to wait for the ready beep signal
before releasing the next shot.
IR filter on the CCD
The IR filter (Phase One TG1 Infrared cut-off filter) is
permanently mounted on top of the CCD.
The filter may not be removed for several reasons:
l
The focusing of the P back camera back will be
damaged.
l
It is only possible to remount the filter without
dust in between the filter and the CCD if you have
access to special clean room facilities.
l
The Phase One Product Warranty is terminated.
