Shooting - Selecting Particular Effects 69
If the shutter speed shows in red on the LCD monitor, the image is under- or
overexposed (insufficient light). Adjust the aperture value using B or A on the
multicontroller until the shutter speed display turns white.
Please note that camera shake becomes a factor at low shutter speeds. If the
camera shake warning
appears in the center of the LCD monitor, secure the
camera to a tripod before shooting.
When using a flash in this mode, the slowest shutter speed is 1/60 second.
