Sharp VIEWCAM VL-NZ50U - Manual (Page 63)

Hints for Better Shooting
• Position the subject in the center of the
scene. When using auto focus, whatever is in
the center of the scene is kept in focus.
Useful Information
For dear, 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.
Lighting
Position the subject in Focus manually when you
the center need to position the
subject off center (see
page 37).
• 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 in this lighting, use
Gamma Brightness Compensation or correct
the exposure level to improve the picture (see
pages 25 and 38),
Light from behind Backlighting
• Before zooming, think about howto best
frame the shot. Frequent zooming produces
unattractive pictures. It also runs down the
battery more quickly,
• When image shaking is 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
In 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.
