Lighting

For clear, good-quality recording, 500 to
100,000 lux is needed. Recording is possible
with less light, but the picture quality may
suffer. Adequate lighting is also essential for
correct white balance.

Useful Information

Hints for Better Shooting

• Position the subject in the center of the

screen. When you are using auto focus,
whatever is in the center of the screen is kept
in focus.

References

Position the subject in

the center.

Focus manually when

you need to position

the subject off center

(see page 44).

Optimal lighting range

• Avoid backlit subjects. For the best picture,

shoot with the light source behind you.
When the background is brighter than the
subject, the subject often becomes too dark.
If you have to record with this lighting, use the
Gamma Brightness Compensation or correct
the exposure level to improve the picture (see
pages 30 and 46).

Light from behind

Backlighting

• Before zooming, think about how to best

frame the shot. Frequent zooming produces
unattractive pictures. It also increases the
battery power consumption.

• When image shakes are noticeable during

zoomed-in telephoto shooting, use a tripod,
or push the Power Zoom control to the W side
to zoom out.

• Horizontal panning (lateral movement) and

tilting (vertical movement) should be done
slowly to emphasize the wide expanse of a
scene or the height of a building, and to
make scenes easy to watch during playback.

• Use a wide-angle setting for fast-moving

subjects.

Note:

• It may take longer to focus when zooming and

panning are used frequently.

Tips on Good Lighting

I

n most outdoor, daytime scenes, natural

lighting is adequate for home videos. Indoors,
however, artificial lighting is usually required.
Video lights with halogen lamps provide the
most natural artificial light over a long operating
life.
