• The nature of CCD image sensors is such that noise in the recorded image
increases at slow shutter speeds. This camera, however, applies special processing

processing time may be required before the next image can be shot.
• At shutter speeds between 1/640 and 1/1000 second, the aperture presets to F8.0.
Shutter Speed Display
The shutter speeds from 1000 to 4 in the display are actually the denominator of a

second and 2" indicates 2 seconds.
