Table 47: Manual gain range for Pike models
Note
•
Setting
the
gain
does
not
change
the
offset
(black
value)
•
A
higher
gain
produces
greater
image
noise.
This
reduces
image
quality.
For
this
reason,
try
first
to
increase
the
brightness,
using
the
aperture
of
the
camera
optics
and/
or
longer
shutter
settings.
