Noise Reduction — Usage restrictions and other notes
• Neither Noise Reduction settings can be used with BSS (
106), brack-
eting (
115), or Continuous settings other than Single (
104).
• If Clear Image Mode
is selected together with an image size of FULL, 3 : 2,
or UXGA, an SXGA image will be recorded, since SXGA is the maximum
permissible size.
• Clear Image Mode works best when the camera and subject are station-
ary. In Clear Image Mode, both the built-in Speedlight and any external
Speedlights are disabled.
Confirming Noise Reduction
While Noise Reduction is in effect and the shutter
speed is below
1
/
30
s, an NR icon appears in the moni-
tor or viewfinder. When set to Clear Image Mode, no
icon is displayed.
Avoiding “Grainy” Pictures: Noise Reduction
When sensitivity (ISO equivalency) is above ISO 100 or
shutter speed is slower than
1
/
30
s , “noise” in the form
of randomly spaced, brightly colored pixels may appear
in pictures, particularly in shadows. Use the options be-
low to reduce noise.
Description
On
Reduces noise in long exposures (speeds of
1
/
30
sec or
slower). The flash can be used, as can all image sizes
settings. Recording time more than doubles.
Clear Image Mode
Minimizes noise and improves color gradation in SXGA
or smaller size images. Pressing shutter-release button
shoots three exposures, two with shutter open, and one
with shutter closed. The three shots are compared to
reduce noise, and one picture is recorded. Recording
time more than triples. Tripod use recommended.
Off
Noise reduction off; camera functions normally.
