F10
Cause/Solution
Shutter speed too slow or ISO sensitivity is high as
the subject is dark. Noise can be reduced by:
• Using flash.
• Specifying a lower ISO sensitivity setting.
When recording movies in dim lighting, the image
may become somewhat "grainy" in appearance.
This occurs when the ISO sensitivity increases, and
it does not indicate a malfunction.
• The flash mode is set to c (Off)
• Flash window is blocked.
• Subject is beyond flash range.
• Adjust exposure compensation.
• Increase ISO sensitivity.
• Subject is backlit. Select Backlighting scene
mode or set the flash mode setting to X (Fill
flash).
Adjust exposure compensation.
When taking pictures with b (Auto with red-eye
reduction) or fill flash with slow sync and red-eye
reduction in Night portrait scene mode, In-
Camera Red-Eye Fix may be applied to areas not
affected by red-eye. Use any scene mode other
than Night portrait, and change the flash mode
to any setting other than b (Auto with red-eye
reduction) and try shooting again.
• Under some shooting conditions, facial skin
tones may not be softened.
• Select e (Skin softening) for Glamour
retouch in the retouch menu for images
containing four or more faces.
It may take more time to save images in the
following situations.
• When the noise reduction function is in
operation.
• When flash mode is set to b (Auto with red-
eye reduction).
• When the skin softening function is applied
while shooting.
When shooting with backlighting or when a very
strong light source (such as sunlight) is in the
frame, colored circles or light streaks (ghosting)
may occur. Change the position of the light source,
or frame the picture so that the light source does
not enter the frame and try again.
