Auto exposure
The Mamiya 645AFD can work in different auto exposure
modes. This is fully supported by the H 10 M645, which com-
municates the equivalent film speed of the digital back to
the Mamiya 645AFD camera.
The default film speed of the H 10 M645 camera back is ISO
50. However this setting can be changed to 100, 200 or even
400 ISO, inside the Capture One application.
It is recommended to capture images using a film curve.
That is done by selecting the film curve in the Capture One
software. Click the camera icon in the icon bar, and select
“Film Curve” or “Film Curve, Natural Black”.
When capturing with auto exposure modes, exposures be-
tween 1/4000 sec. and 30 sec can be obtained. Please note
that images captured with exposure times longer than 2 sec.
can be degraded because of increased digital noise.
