17.3 More Details: Contax 645
Exposure Modes
The Contax 645 manual (M) and semi-auto exposure modes (Av, Tv)
are fully supported by the Leaf Credo back. Please note that Bulb is
only supported on Contax/Leaf Credo back when used in conjunction
with the Live View function. Go to Chapter 19 (from page 142) for more
information about Live View.
Check the relevant Contax 645 manual for more information on exposure
modes.
Ensure that exposure times are limited between 1/4000 second and
approximately one second to obtain the highest possible quality with a
Leaf Credo back and Contax 645. Please note that it is not possible to
expose images longer than two minutes with a Leaf Credo 80 and 60
seconds with a Leaf Credo 60 or 40.
ISO Settings
The Contax 645 exposure modes use the ISO value set in the Leaf
Credo back. The ISO setting can be adjusted from the camera back or in
Capture One software when shooting tethered.
Consult page 24 of this manual for details on setting the ISO. Go to page
49 for more information about tethered shooting.
Double Exposure Protection
It is not possible to accidently double expose an image by capturing one
image quickly after another when a Leaf Credo back is used on a Contax
645 e.g. when using the continuous drive mode.
