Gain - Sony PXW-FS7 Manual

Gain

Gain is an electronic amplification of the video signal. This means that the signal is boosted
electronically, adding more voltage to the pixels on your imager (CCD or CMOS) causing them to
get amplify their intensity and therefore brighten your image.
Gain is measured in db with the
following values and what they mean in
terms of how many stops of light do
they add
L +6dB = Adds 1 F Stop
M +12dB = Adds 2 F Stops
H +18dB = Adds 3 F Stops
On the left hand side there is a switch
that has 3 positions (L,M,H). These
values can be changed by going to
Menu > Camera > ISO/Gain/EI > You
will see the options to change low,
medium and high
