4.2 General Hardware Setup
Powering up the Leaf Credo back
After a Leaf Credo back is connected to a camera body, insert a battery,
USB 3.0 or FireWire 800 cable and it automatically turns on. The back is
switched on/off by pressing the power button located at the top of the
Leaf Credo back.
ISO Settings
The Credo 80 back has a default ISO range from ISO 35-800. The Credo
60 and Credo 40 have a default ISO range from ISO 50-800. An ISO
rating can be selected from the menu system (when untethered) or in the
Capture Tool in Capture One Pro software (when tethered).
Shutter Latency
The default setting is Normal Latency, which should remain unchanged
under all ‘normal’ shooting scenarios. Only change the setting to
Zero
Latency
if you work on technical cameras, large format cameras or
certain manual cameras in special situations.
Double Exposure Protection
It is not possible to accidentally double expose an image by capturing one
shot quickly after another when a Leaf Credo back is used on cameras
such as the Mamiya 645DF+/AF/AFDIII, Phase One 645DF+, Hasselblad
555 ELD (DIG mode), Hasselblad H or Contax 645. The electronic
communication with the body ensures that the Leaf Credo back is ready
before allowing release of the next shot. However, users of other camera
bodies that do not use the electronic interface from the Credo have to
wait for the ready beep signal before releasing the next shot.
