Live view ends unexpectedly or does not start: Live view may end automatically to prevent damage to the camera's internal circuits if: • The ambient temperature is high • The camera has been used for extended periods in live view or to record movies • The camera has been used in continuous release modes for extended periods If live view does not start when you press the a button, wait for the internal circuits to cool and then try again. Note that the camera may feel warm to the touch, but this does not indicate a malfunction. Image artifacts appear during live view: The temperature of the camera's internal circuits may rise during live view, causing image "noise" in the form of bright spots, randomly-spaced bright pixels, or fog. Exit live view when the camera is not in use. 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 supply (0 371). Bright bands appear during live view or movie recording: A flashing sign, flash, or other light source with brief duration was used during live view or movie recording. Noise (bright spots, randomly-spaced bright pixels, fog, lines, or reddish areas) appears in photos: • To reduce randomly-spaced bright pixels, fog, or lines, choose lower ISO sensitivity or use high ISO noise reduction (0 109, 299). • To reduce bright spots, randomly-spaced bright pixels, or fog at shutter speeds slower than 1 s or to reduce reddish areas and other artifacts in long time-exposures, enable long exposure noise reduction (0 299). • Turn Active D-Lighting off to avoid heightening the effects of noise (0 183). 462
