BASIC IMAGE RECORDING I Recording Precautions • Never open the battery cover or place the camera onto the USB cradle while the operation lamp is flashing green. Doing so not only causes the current image to be lost, it can also corrupt images already stored in file memory and even lead to malfunction of the camera. • Never remove the memory card while an image is being recorded to the memory card. • Fluorescent lighting actually flickers at a frequency that cannot be detected by the human eye. When using the camera indoors under such lighting, you may experience some brightness or color problems with recorded images. • When "Auto" is selected for the ISO sensitivity setting (page 99), the camera automatically adjusts its sensitivity in accordance with the brightness of the subject. This can cause some digital noise (graininess) to appear in images of relatively dark subjects. • When recording a dimly lit subject while "Auto" is selected for the ISO sensitivity setting (page 99), the camera increases sensitivity and uses a slower shutter speed. Because of this, you need to guard against camera movement if you have flash turned off (page 58). • Bright light shining on the lens can cause images to appear "washed out". This tends to happen when recording images outdoors in bright sunlight. To protect against this, use your free hand to shade the lens from the light.

BASIC IMAGE RECORDING

Recording Precautions
Never open the battery cover or place the camera onto
the USB cradle while the operation lamp is flashing
green. Doing so not only causes the current image to be
lost, it can also corrupt images already stored in file
memory and even lead to malfunction of the camera.
Never remove the memory card while an image is being
recorded to the memory card.
Fluorescent lighting actually flickers at a frequency that
cannot be detected by the human eye. When using the
camera indoors under such lighting, you may experience
some brightness or color problems with recorded images.
When
Auto
is selected for the ISO sensitivity setting
(page 99), the camera automatically adjusts its sensitivity
in accordance with the brightness of the subject. This can
cause some digital noise (graininess) to appear in images
of relatively dark subjects.
When recording a dimly lit subject while
Auto
is selected
for the ISO sensitivity setting (page 99), the camera
increases sensitivity and uses a slower shutter speed.
Because of this, you need to guard against camera
movement if you have flash turned off
(page 58).
Bright light shining on the lens can cause images to
appear
washed out
. This tends to happen when
recording images outdoors in bright sunlight. To protect
against this, use your free hand to shade the lens from
the light.
About Auto Focus
Auto Focus tends not to work well if the camera is moved
during recording, or when recording the types of subjects
listed below.
Solid color walls or subjects with little contrast
Strongly backlit subjects
Polished metal or other brightly reflective subjects
Venetian blinds or other horizontally repeating patterns
Multiple subjects that are varying distances from the
camera
Subjects in poorly lit areas
Moving subjects
Note that a green operation lamp and focus frame do not
necessarily guarantee that the resulting image will be in
focus.
If Auto Focus does not produce the results you want for
some reason, try using focus lock (page 74) or manual
focus (page 73).
