BASIC IMAGE RECORDING
About the REC Mode Monitor Screen
The image shown on the monitor screen in the REC
mode is a simplified image for composing purposes. The
actual image is recorded in accordance with the image
quality setting currently selected on your camera. The
image saved in file memory has much better resolution
and detail than the REC mode monitor screen image.
Certain levels of subject brightness can cause the
response of the REC mode monitor screen to slow down,
which causes some static noise in the monitor screen
image.
Recording Precautions
Never open the battery cover or place the camera onto
the USB cradle while the operation/flash charge lamp is
flashing. 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 70), the camera automatically adjusts its sensitivity
in accordance with the brightness of the subject. This can
cause some static noise to appear in images of relatively
dark subjects.
When “Auto” is selected for the ISO sensitivity setting
(page 70), the camera raises the sensitivity and uses a
faster shutter speed. Because of this, you need to guard
against camera movement if you have flash turned off
(page 47) when recording a dimly lit subject.
If unwanted light is shining on the lens, shade the lens
with your hand when recording the image.
