Shutter Speed Display - Canon POWERSHOT S2 IS User Manual

• If the image would be underexposed (too dark) or overexposed (too bright)
and the correct exposure cannot be obtained, the aperture value display on
the LCD monitor (or viewfinder) turns red. Adjust the shutter speed with the
or • button so that the aperture value display turns white.
• The nature of CCD image sensors is such that noise in the recorded image
increases at stow shutter speeds. This camera, however, applies special
processing to images shot at shutter speeds slower than 1.3 seconds to
eliminate the noise, thereby producing high-quality images. Nevertheless, a
certain amount of processing time may be required before the next image
can be shot.
• The aperture value and shutter speed change according to the zoom state as
follows.
