Canon SD100 User Manual (en)

• When you use flash photography at higher ISO speeds, the chances 
of white streaks appearing in the image increase the closer you 
approach to the subject.
• Since a slow shutter speed is selected in dark places when the flash 
is set to Off or Slow-Synchro, take care to avoid blurring the image.
- Shooting in 
Be careful to hold the camera still to avoid camera shake.
- Shooting in 
Fix the camera to a tripod to shoot in these modes since the 
shutter speed will be slower than in the 
 mode. If an image is 
dark in 
 mode, reshooting it in 
 mode will make it brighter.
• The flash can be fired when the upper indicator beside the 
viewfinder lights a steady orange after pressing the shutter button 
• The flash may take up to approximately 10 seconds to charge. The 
recharging time will vary with such factors as the shooting 
conditions and battery charge. Shots cannot be taken while the flash 
is charging.
• The flash fires twice. The main flash follows a preparatory pre-flash. 
The exposure reading obtained from the subject with the pre-flash is 
used to set the optimal flash intensity for the main flash, which is 
used to capture the image.
Red-Eye Reduction
• Light reflecting back from eyes can make them appear red when the 
flash is used in dark areas. Under these conditions, use the red-eye 
reduction mode. For this mode to be effective, the subject must be 
looking right at the red-eye reduction lamp. Try asking them to look 
directly at the lamp. Even better results can be obtained by shooting 
with the lens set to a wide angle, increasing the lighting in indoor 
settings or approaching closer to the subject.
• The shutter will not activate for approximately 1 second after the red-
eye reduction lamp fires in order to improve the effect. If you want a 
more immediate shutter response, set the flash to
