MEMO

● To reduce the flickering which occurs under fluorescent lighting, set the shutter speed to 1/50 if your local power supply frequency is 50 Hz and to 1/120 if it is 60 Hz.

● When a high shutter speeds are used, white stripes may be observed above and below bright objects. This is called the smear phenomenon and is usual to CCD cameras.
