Gain adjustment
e camera has a video gain circuit that ampli es the
video signal in order to make it possible to shoot in
very low light situations. e side-effect of video gain
is that the image will exhibit considerable more noise,
therefore, you only want to shoot at high gain
settings when it's absolutely necessary.
To manually set the gain, make sure the AUTO/
MANUAL switch to set to manual mode.
Switch the gain using the GAIN switch on the side of
the camera, with the default camera settings the three
positions are:
Introduction to the Panasonic AG-HMC150 AVCHD camcorder (rough draft)
You can change the amount of video gain that
corresponds to the M and H switch settings by
changing the MID GAIN and HIGH GAIN items in
the SW MODE settings menu. If the AGC item on
the AUTO SW settings menu is set to anything other
than OFF, the gain setting will be set to automatic
during automatic mode, regardless of the position of
the GAIN switch.
When a slow shutter speed (e.g. 1/15) is set, the gain
is xed at 0 dB gain regardless of the position of the
GAIN switch.

ND lter adjustment
Sometimes you'll nd yourself shooting in conditions
with too much light. You want to avoid shooting
with lens apertures of f/11 or f/16 if you can avoid it,
because at these settings lens performance suffers due
to excessive refraction. e sweet spot in terms of
maximum sharpness for the lens on this camera is
around f/4 or so. In order to open up the lens in
bright shooting conditions, the camera is going to
need the equivalent of sunglasses and here's where the
ND (neutral density) lter comes it. It's a colorless
lter that reduces the intensity of the light entering
the camera. e ND FILTER switch can be set to
one of the following settings:

L: For shooting under normal lighting conditions
(0 dB video gain)
M: For shooting in low light conditions (6 dB
video gain)
H: For shooting in very low light conditions (12
dB video gain)
OFF: e ND lter is not engaged
1/4: Reduces light intensity by 1/4 (2 stops)
1/16: Reduces light intensity by 1/16 (4 stops)
1/64: Reduces light intensity by 1/64 (6 stops)
