788 Problems and Solutions
Image artifacts appear in the display during shooting:
• To reduce noise, adjust settings such as ISO sensitivity, shutter speed,
or Active D-Lighting.
• At high ISO sensitivities, noise may become more noticeable in long
exposures or in pictures recorded when the camera temperature is
elevated.
• Randomly-spaced bright pixels, fog, or bright spots may arise as a
result of increases in the temperature of the camera’s internal circuits.
Turn the camera off when it is not in use.
• Randomly-spaced bright pixels, fog, lines or unexpected colors may
appear if you press the
X button to zoom in on the view through the
lens during shooting.
• Note that the distribution of noise in the display may differ from that in
the final picture.
• This issue can sometimes be addressed by checking and optimizing
the image sensor. Perform pixel mapping using [
Pixel mapping ] in the
setup menu.
The camera cannot measure a value for preset manual white
balance:
The subject is too dark or too bright.
Certain pictures cannot be selected as sources for preset manual
white balance:

preset manual white balance.
White balance (WB) bracketing is unavailable:

JPEG option is selected for image quality.
