The IVS can change the brightness of the video image 

electronically. This gain control can be automatic or manual. 

If the automatic control is selected, the IVS outputs the best 

possible image brightness at all the time. Light changes in 

front of the film camera are compensated by the IVS; the 

brightness impression remains almost unchanged.

Gain control can be adjusted in two different ways. 

It is possible to control it using the keyboard on the IVS or 

using the on-screen control menu.

•  By pressing the WB key Ï the setting alters between 

manual and automatic control. An illuminated LED shows 

the setting manual gain control (MGC) 

➪ 

.

•  If manual gain control is selected (LED is on), the 

brightness of the video image can be manually altered. 

By using the Ê or Ë key brightness can be increased 

or decreased. An automatic compensation of different 

light levels in front of the camera is suppressed.
