Large format photography
The Phase One H 25 can be used on most large format
cameras via the optional Phase One FlexAdaptor and supports
all mechanical shutters and the Horseman ISS electronic
shutter. To ensure optimal image quality, Phase One strongly
recommends shutters that can be fired twice within four
seconds. The first release of the shutter activates the CCD,
the second release takes the picture. If the time limit of four
seconds is exceeded, the camera gives a warning “beep”
followed by a “ready” signal. If for some reason it is not
possible to fire the shutter twice within the time limit, the
camera will send a time-out error message to the screen.
