Description of settings
([Forced Flash On]) The flash is activated every time regardless of the recording 
conditions.
Use this when your subject is back-lit or under 
fluorescent light.

Red-Eye])

([Slow Sync.])
When taking pictures against a dark background landscape, 
this feature will slow the shutter speed when the flash is 
activated. Dark background landscape will appear brighter.
Use this when you take pictures of people in front of a 
dark background.
Using a slower speed can cause motion blur. Using a 
tripod can enhance your photos.

used.
