Hide Menu
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.
