Phase One 645 AF Digital Camera User Manual


 
69
In general, if the camera is used with medium format cameras with
digital interface the setting can be either “Short latency” or “Long
latency”.
Short latency has a shorter response time, but is power consuming, so
when battery time is an issue you should select “Long latency” on the
cost of response time from the camera.
If the P+ back is used in “two shoot mode” on a large format camera
with i.e. a copal shutter or another mechanical shutter where the
shutter is released one time for waking up the back, and another time
for shooting the image, then the shutter setting in the P+ back should
be set to “long latency”.
While short latency will respond immediately to triggering the camera,
Long latency will not be that fast, but in return you gain much longer
battery power.
FileFormat
In “FileFormat” you can select two options “IIQ Raw L” and “IIQ Raw S”.
“IIQ Raw” is a short term for Intelligent Image Quality Raw.
“IIQ Raw L” is set as the default and is the loss less capture format of
the P+ back.
“IIQ Raw S” is a smaller le, and not totally loss less in the format. The
“IIQ Raw L” is approximately 1/3 le size of the processed TIFF le.
“IIQ Raw S” is approximately 1/5 of the processed TIFF. Most users will
use the “IIQ Raw S” as there is virtually no quality difference between
the two settings.
Please consult the camera specic sections in this manual to learn
more about how to use shutter latency with your particular P+ back
setup.
