Canon PowerShot SD500 Guida Utente

• When you use the flash 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 camera shake. You 
are recommended to shoot with the camera fixed to a tripod or other 
device if the camera shake warning icon 

 appears.

• The flash can be fired when the indicator lights a steady orange after 

pressing the shutter button halfway.

• 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 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. 

• When using the flash for standard photography, be sure to shoot 

from a distance of at least 50 cm (1.6 ft.) away from your subject.

• 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 
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

The selected flash mode appears on the LCD 
monitor.
