Noise (bright spots, randomly-spaced bright pixels, fog, or lines) appear in photos:
• Bright spots, randomly-spaced bright pixels, fog, and lines can be
reduced by lowering ISO sensitivity.
• Use the Long exposure NR option in the shooting menu to limit the
occurrence of bright spots or fog in photos taken at shutter speeds
slower than 1 s (0 230).
• Fog and bright spots may indicate that the camera's internal
temperature has become elevated due to high ambient temperatures,
long exposures, or similar causes: turn the camera off and wait for it to
cool before resuming shooting.
• At high ISO sensitivities, lines may appear in photos taken with some
optional flash units; if this occurs, choose a lower value.
• At high ISO sensitivities, including high values selected with auto ISO
sensitivity control, randomly-spaced bright pixels can be reduced by
selecting High, Normal, or Low for High ISO NR in the shooting menu
(0 231).
• At high ISO sensitivities, bright spots, randomly-spaced bright pixels,
fog, or lines may be more noticeable in long exposures, and photos
taken at high ambient temperatures or with Active D-Lighting enabled,
Flat selected for Set Picture Control (0 155) or extreme values
selected for Picture Control parameters (0 158).
• In % mode, randomly-spaced bright pixels, fog, or lines may be more
noticeable in pictures shot under low light.
Can not choose a release mode: Release mode selection is not available when
the monitor is off (0 75). Note that the eye sensor may turn the monitor
off automatically when you put your eye to the viewfinder.
