Adjusting The Brightness; Using The Ae Function - Sony PMW-10MD Operating Instructions Manual

Adjusting the Brightness

This unit has an AE function that automatically
adjusts brightness through a combination of
adjustments to the total gain of the video amp and
shutter speed settings. You can also adjust the
brightness by using the BRIGHTNESS knob,
which also adjusts brightness through a
combination of total gain and shutter speed
settings. If you need to make manual adjustments
for special shooting conditions, you can set the
total gain and the shutter speed separately in the
Picture Profile menu.

Using the AE function

To turn the AE function on, press the AE button,
lighting it. The camera controls brightness by
switching automatically, according to shooting
conditions, between AGC (auto gain control)
mode and auto shutter mode.
Use "AE" (see page 46) in the Picture Profile
menu to set the adjustment level (AE level), the
adjustment mode, and the upper and lower limits
for AE function setting values.
To specify how light is measured before adjusting
the brightness, you can select from among five
light measurement areas.

Setting the AE level
The AE level sets the automatic brightness
adjustment level, by specifying how much
brighter or darker it is than the standard level.
You can set the AE level with "AE" >"Level"
(see page 46) in the Picture Profile menu.
When the AE function is on, you can also rotate
the BRIGHTNESS knob to set the AE level.
Rotate it clockwise to increase the AE level
(make it brighter than the standard level) and
rotate it counterclockwise to decrease the AE
level (make it darker than the standard level). To
reset the AE level to the factory-default value,
you can hold down the BRIGHTNESS knob for
one or more seconds.
