PowerShot S200, Digital IXUS V2 Camera User Guide

Basic Functions
35
Pressing Fully
Pressing the shutter button down fully activates the shutter and causes
one shutter sound to sound.
• While the image is being recorded to
the CF card, the indicator flashes green.
• AF-assist Beam
- The AF-assist Beam will sometimes emit when the
shutter button is pressed halfway to assist focusing in
certain conditions, i.e., dark conditions.
- The AF-assist Beam can be turned off (p. 118). If animals
are your subject, turn off the beam when shooting in
the dark to avoid startling them (this may however,
make it more difficult for the camera to focus).
