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 photo shooting menu to limit
the occurrence of bright spots or fog in photos taken at shutter speeds
slower than 1 s (0 313).
• 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 photo or movie
shooting menu (0 314, 320).
• At high ISO sensitivities, bright spots, randomly-spaced bright pixels, fog,
or lines may be more noticeable in long exposures, multiple exposures,
and photos taken at high ambient temperatures or with Active
D-Lighting enabled, Flat selected for Set Picture Control (0 179) or
extreme values selected for Picture Control parameters (0 182).
Flicker or banding appears during live view or movie recording: Choose an option for
Flicker reduction that matches the frequency of the local AC power

Bright regions or bands appear in live view: A flashing sign, flash, or other light
source with brief duration was used during live view.
