If the on-screen program mode is on because the settings
are changed, the Menu (M) position clears the screen. For
example, if color is to be changed with the on-screen
program tool, the on-screen program window overlays
the image. To see the image and its color appearance, go
to M position. The window disappears but the on-screen
program mode is still on. By releasing the switch, the
window will come back in the programming mode.
10.3.2 Mechanical Iris
Only a relatively small portion of the light that passes
through the film camera’s lens reaches the CCD-Chip of
the video assist, as the light is shared between the view
finder, the CCD-Chip and the film. Therefore the IVS
lenses are designed for normal usage with a totally open
iris to have maximum light on the CCD-Chip. Variations
in lighting are compensated by the IVS gain control
(automatically or manually).
Under certain conditions, such as when lighting is set for
low sensitivity film (under 100 ASA) or for motion effects,
it is possible that the IVS gain range is exceeded. In this
case the mechanical iris of the IVS lens can be closed.
