Flicker Reduction
If Auto fails to produce the desired results and you are unsure as to the
frequency of the local power supply, test both the 50 and 60 Hz options
and choose the one that produces the best results. Flicker reduction
may not produce the desired results if the subject is very bright, in which
case you should try choosing a smaller aperture (higher f-number). To
prevent flicker, select mode h and choose a shutter speed adapted to the
frequency of the local power supply:
