Photographs and movies do not appear to have the same exposure as the preview shown in the display: To preview the effects of changes to settings that affect exposure and color, select On for Custom Setting d8 (Apply settings to live view). Note that changes to Monitor brightness and Viewfinder brightness have no effect on images recorded with the camera. Flicker or banding appears in movie mode: Select Flicker reduction in the movie shooting menu and choose an option that matches the frequency of the local AC power supply. Bright regions or bands appear in the view through the lens: The shot is being framed under flashing sign, flash, or other light source with brief duration. Smudges appear in photographs: Clean the front and rear lens elements. If the problem persists, perform image sensor cleaning. Bokeh is irregular: With fast shutter speeds and/or fast lenses, you may notice irregularities in how bokeh is shaped. The effect can be mitigated by choosing slower shutter speeds and/or higher f-numbers. Shooting ends unexpectedly or does not start: Shooting may end automatically to prevent damage to the camera's internal circuits if the ambient temperature is high or the camera has been used extensively for burst shooting, movie recording, or the like. If you are unable to shoot because the camera has overheated, 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 in the display during shooting: "Noise" (randomly-spaced bright pixels, fog, or lines) and unexpected colors may appear if you zoom in on the view through the lens. Randomly-spaced bright pixels, fog, or bright spots may also arise as a result of increases in the temperature of the camera's internal circuits during shooting; turn the camera off when it is not in use. At high ISO sensitivities, noise may become more noticeable in long exposures or in pictures recorded when the camera temperature is elevated. Note that the distribution of noise in the display may differ from that in the final picture. To reduce noise, adjust settings such as ISO sensitivity, shutter speed, or Active D-Lighting. 392 Troubleshooting
