Notes on recording in manual mode
• We recommend that you adjust the focus and white balance manually.
• Depending on the shutter speed, a screen may flicker and a color of screen may
change when you record under the illumination by a discharge tube such as a
fluorescent lamp, a sodium light and a mercury lamp. In such a case, fix shutter speed
in 1/100 in an area of 50 Hz and in 1/60 in an area of 60 Hz.
Relation of aperture, shutter speed and gain
While recording, a picture’s brightness varies by exposure, you need to keep the
exposure fixed to obtain a fixed brightness.
Total EV (exposure) = EV from aperture control
+ EV from shutter speed control
+ EV from gain control
When to adjust aperture, shutter speed, and gain manually
When selecting one of aperture, shutter speed, or gain to be adjusted manually and
leaving the remaining two in automatic adjustment, the remaining two automatic
settings adjust their values based on the value of that one manual setting.
In the following cases, you should obtain better results by adjusting setting manually.
[a] Shooting portraits – adjust aperture manually.
To alter the depth of focus field, softening the background and making the subject
stand out, portrait style.
[b] Shooting sporting events – adjust shutter speed manually.
•To record fast moving objects and protect against blurring of subject.
•To brighten subject in dark situations.
•To prevent the aperture from closing down in unusually bright situations.
[c] Shooting dark environments – adjust gain manually.
•To suppress color distortion when shooting bright objects in dark places.
•To protect against picture distortion when shooting bright objects.
