˔ 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. ˔ The upper portion of the shooting display dims during burst photography: This phenomenon may occur when the mechanical shutter is used but has no effect on the pictures taken. ˔ 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: Pictures created with cameras of other types cannot serve as sources for preset manual white balance. ˔ White balance (WB) bracketing is unavailable: • White balance bracketing is not available when an NEF (RAW) or NEF + JPEG option is selected for image quality. • White balance bracketing cannot be used in multiple exposure and HDR modes.
