A Flicker Reduction in the Photo Shooting Menu Take a test shot and view the results before taking additional photographs. Flicker reduction can detect flicker at 100 and 120 Hz (associated respectively with AC power supplies of 50 and 60 Hz). Flicker may not be detected or the desired results may not be achieved with dark backgrounds or bright light sources. In the case of decorative lighting displays and other non-standard lighting, the desired results may not be achieved even when the FLICKER icon is displayed. Depending on the light source, there may be a slight delay before the shutter is released. During burst shooting, the frame rate may slow or become erratic; in addition, the desired results may not be achieved if the frequency of the power supply changes during shooting. Flicker detection is performed whenever the composition is changed, which may result in the FLICKER icon being displayed intermittently. Flicker detection may not take effect at shutter speeds slower than 1/100 s (including Bulb and Time) or when MUP is selected for release mode or exposure delay mode is on. Flicker detection is available during flash photography but can not be used with remote wireless flash units. 235
