Shooting
Adjusting the ISO Speed
Raise the ISO speed when you wish to reduce the effects of camera shake, 
turn the flash off when shooting in a dark area, or use a fast shutter speed.
• Higher ISO speeds increase image noise. To take clean images, use as 
low an ISO speed as possible.
• The AUTO setting selects the optimal speed. It will automatically 
raise the speed when the light from the flash is insufficient to 
illuminate the subject matter.
See Photo Tips and Information (p. 181).
